During cross-examination by defendants of State’s witness Oldham each defendant brought out that Oldham was addicted to valium. Defendant Cummings also brought out on cross-examination that Oldham had tried other drugs, including cocaine. Then on re-direct examination the State was permitted to bring out that Oldham gave defendant Cummings about twenty-five per cent of the valium he bought. Also on re-direct examination Oldham was permitted to testify that, after the first trip to New Hill to view the Holland’s store and residence, he took cocaine which he obtained from Wallace (Skeeter) Logner.
[1] Defendant Cummings undertakes to assign error to the admission of testimony on re-direct examination of the State’s witness Oldham concerning valium supplied by Oldham to Cummings. Defendants Logner and Williams do not object to the redirect testimony concerning valium. Defendant Cummings waived objection to testimony about the valium by failure to enter timely objection or motion to strike. State v. Little, 278 N.C. 484, 180 S.E. 2d 17 (1971); Stansbury’s N.C. Evidence, § 27, p. 70 (Brandis Rev. 1973). The following transpired on re-direct examination of State’s witness Oldham:
“Redirect Examination By Mr. Hall [District Attorney]:
When Mr. Oldham engaged in criminal activity, he usually had more than one other person with him. Of the $100,000.00 of property he admitted to stealing, his share approximated $25,000.00. He did not take all the valium he got prescriptions for.
Q. Who else took any of it?
A. I gave Ray Cummings part of it. I gave Chester Estes part of it.
*545Q. What percentage of it would you say that you gave Ray Cummings?
MR. CRUMPLER: Objection.
Court: Overruled.
Cummings’ exception No. l.
A. I would say approximately twenty-five percent of what I bought.”
Having failed to object to the first question about who else took any of the valium, and particularly having failed to move to strike the testimony that Oldham gave Cummings part of it, defendant Cummings’ objection to the question as to the percentage given to Cummings came too late. We perceive no harm in the witness answering that he gave Cummings twenty-five per cent of the valium he bought after he had already testified without objection that he had given Cummings part of the valium. This assignment of error by defendant Cummings is overruled.
[2] Defendants Logner and Williams assign as error the admission of the testimony concerning cocaine on re-direct examination. Defendant Cummings does not object to the re-direct testimony concerning cocaine.
“When a conspiracy is established, everything said, written, or done by any of the conspirators in execution or furtherance of the common purpose is deemed to have been said, done or written by every one of them, and may be proved against each.” State v. Summerlin, 232 N.C. 333, 337, 60 S.E. 2d 322, 325 (1950). “It is undoubtedly the general rule of law that evidence of a distinct substantive offense is inadmissible to prove another and independent crime, the two being wholly disconnected and in no way related to each other.” Id. However, if the evidence tends to prove any other relevant fact it will not be excluded merely because it also shows the accused to have committed an independent crime. 1 Stansbury’s, supra, § 91, p. 288. If the evidence of other crimes bears some logical relevance to the crime charged it will be admitted. See State v. Fowler, 230 N.C. 470, 53 S.E. 2d 853 (1949).
*546The testimony concerning cocaine was restricted by the trial judge to events which took place after the planning of the robbery began. The trial judge ruled in effect that the evidence was relevant as a part of the on-going conspiracy. It may also have been relevant to establish the close relationship between State’s witness Oldham and Wallace (Skeeter) Logner to support Oldham’s identification of Logner as a participant in the crime for which he was being tried.
Defendant Williams argues that even though the evidence that State’s witness Oldham obtained the cocaine from defendant Logner may have been admissible against defendants Logner and Cummings, it was nevertheless inadmissible against him because the evidence of the conspiracy did not implicate him until the day of the robbery when he was secured as a substitute driver.
It is immaterial when a defendant entered into or became a party to the conspiracy, or how prominent or inconspicuous a part he took in the execution of the unlawful purpose; he is responsible to the fullest extent for everything that is said and done in furtherance of the plot. State v. Summerlin, supra.
Conceding arguendo that it was error to admit the re-direct testimony that Oldham on one occasion had obtained cocaine from defendant Logner, we fail to perceive how the testimony reasonably could have prejudiced Logner and Williams in this trial for murder, kidnapping, conspiracy to commit armed robbery, and armed robbery to the extent that it caused a result different from that which would have been reached had the testimony been excluded. The primary controversy throughout this trial was the credibility of State’s witness Oldham and defendants were afforded every opportunity to discredit him. It seems to us that the mere mention of cocaine one time was insignificant in a trial as protracted as this one. In our opinion the error in admitting the one brief statement that Oldham had obtained cocaine from defendant Logner could not have prejudiced defendants Logner and Williams so as to raise a “reasonable possibility that, had the error in question not been committed, a different result would have been reached. . . .” G.S. § 15A-1443. See State v. Cross, 284 N.C. 174, 200 S.E. 2d 27 (1973).
This assignment of error by defendants Logner and Williams to the admission of the testimony concerning cocaine on re-direct examination is overruled.
*547 [3] All defendants assign as error that the trial judge allowed “the prosecutor to conduct redirect examination of the witness Oldham with respect to a separate robbery-homicide that the witness admitted participating in with another unnamed person.”
On cross-examination by defendants the State’s witness Oldham testified that he was presently serving a twenty year sentence for safecracking; that he had broken into at least one hundred homes and businesses; that he was fifteen or sixteen years of age when he was first arrested; that between the ages of sixteen and thirty-three he had netted at least $100,000.00 from stealing and robbing; and that he participated with another person in the robbery and murder of Mr. and Mrs. A. B. Lee in Johnston County about three weeks before the robbery-murder involved in this case. The cross-examination of the State’s witness Oldham concerning his past conduct was permissible and proper for the purpose of impeaching his credibility as a witness. However, defense counsel also launched into completely irrelevant cross-examination concerning the names of persons who had participated in criminal activity with Oldham. Oldham was permitted to testify on cross-examination, without objection from anyone, that Bobby Blackman and Jimmy Blackman had participated with him in criminal activity; that Bobby Blackman is presently serving a prison sentence for a homicide; that Richard Godwin had participated in four crimes with him; that Charles Estes has robbed as many as twenty-five places with him; that his brothers Anthony and Keith Oldham were involved with him in some robberies in Chatham County; and that he and Roscoe Grice discussed the robbery and murder of Mr. and Mrs. Lee in Johnston County, although Grice did not actually participate.
It appears from the record on appeal that Oldham had, in his conversations with an S.B.I. agent, implicated defendant Cummings in the murder-robbery of Mr. and Mrs. Lee in Johnston County. In response to defendant Cummings’ motion to suppress such testimony by State’s witness Oldham, the district attorney properly instructed Oldham not to mention Cummings’ participation in the Johnston County murder-robbery. This instruction was followed by Oldham. Therefore defendants were safe in launching into the irrelevant cross-examination concerning others who had participated in crime with him. But that safety for Cummings did not render the irrelevant cross-examination proper. Such cross-*548examination was apparently engaged in to lay the ground for the spurious argument to the jury by defendants that since those other persons had engaged in crimes with Oldham that the jury more reasonably should believe that it was one or more of those persons who had participated with Oldham in the Johnston County robbery-murder and also in the robbery-murder of Mr. Holland in Wake County instead of the three defendants.
On re-direct examination by the district attorney Oldham testified that he and one other person were present at the robbery-murder of Mr. and Mrs. Lee in Johnston County. The district attorney then asked a series of questions, and, over objection by defendants to each question, Oldham was permitted to testify that it was not Chester Estes, that it was not Anthony or Keith Oldham, that it was not Bobby Blackman, and that it was not Jimmy Blackman who was present with him at the time of the Johnston County robbery-murder. These questions and answers, like defendants’ cross-examination, were irrelevant to the subject matter of the trial. However, defendants by their cross-examination clearly opened the door to the questions on re-direct examination and should not be heard to complain. G.S. § 15A-1443(c). In any event none of the questions or answers, of which defendants complain, in any way implicated defendants in the independent substantive offenses of the robbery and murder of Mr. and Mrs. Lee in Johnston County.
Following the above line of questioning the district attorney, with further irrelevant questions, brought out that the other person with Oldham in the Johnston County robbery-murder was not from Lee County. Then all defendants objected to Oldham being allowed to testify that the other person was not from Chatham County and was not from Johnston County. It seems that defendants in their cross-examination of Oldham and the district attorney in his re-direct examination lost sight of the fact that the crime in question was the robbery-murder of Mr. Holland in the New Hill section of Wake County. Defendants and the State undertook an investigation of the Johnston County robbery-murders.
Defendants argue from the false premise that allowing Oldham to testify that the other person with him in the Johnston County robbery-murders was not from Chatham County or from *549Johnston County (they did not object to his testimony that the other person was not from Lee County) necessarily reflected that the other person must have been from Durham County (home county of the defendants) and therefore implicated one of them as being the other participant. This argument is specious. Under the testimony of which defendants now complain the other person in the Johnston County robbery-murders could have as easily come from any one of the other one hundred counties of the State or even beyond the borders of the State.
Following the above line of questioning the district attorney, still on re-direct examination of Oldham about the Johnston County robbery-murders, asked if the other person with Oldham was armed and with what. Over objection from all defendants, Oldham was allowed to answer that the other person was armed with a .22 cal. rifle. Conceding that the questions and answers were irrelevant to the charges being tried, it is inconceivable how defendants were harmed. Defendants had already brought out on their irrelevant cross-examination that the other person with Oldham shot Mr. Lee with a . 22 cal. rifle.
The admission of technically incompetent evidence is harmless unless it is made to appear that defendants were prejudiced thereby and that a different result likely would have ensued had the evidence been excluded. State v. Barbour, 278 N.C. 449, 180 S.E. 2d 115 (1971). Our judgment must be based on our own reading of the record on appeal and on what seems to us to have been the probable impact of this irrelevant testimony on the minds of an average jury. Harrington v. California, 395 U.S. 250, 89 S.Ct. 1726, 23 L.Ed. 2d 284 (1969). Viewing the record on appeal in its entirety this irrelevant testimony brought out by the State was of no probative value for any purpose and could not have prejudiced defendants. Also, as pointed out, defendants opened the door for this irrelevant testimony by bringing out substantially the same irrelevant testimony themselves. This assignment of error is without merit and is overruled.
[4] The defendants assign as error that the trial court permitted the State to offer in evidence telephone company records, which indicated that there had been numerous telephone calls between defendant Cummings and Oldham between 19 February 1977 and 7 March 1977 (the date of the robbery-murder of Mr. Holland in Wake County).
*550Oldham testified that he had known defendant Logner for two years prior to 7 March 1977; that he had known defendant Cummings three to four years prior to 7 March 1977; that he had known defendant Williams for two to three weeks prior to 7 March 1977; and that he knew where each of the three lived in Durham. Oldham further testified that he had talked to defendant Cummings on the telephone from his (Oldham’s) residence in the Bear Creek Community of Chatham County on several occasions, including a call from Cummings on 7 March 1977 in which Cummings told him they needed to go back “down yonder,” and told Oldham to bring this shotgun.
The telephone records were identified and duly authenticated by qualified officials of the General Telephone Company of the Southeast (serving Durham) and of United Telephone Company for the Carolinas (serving the Bear Creek Community of Chatham County). These records were for the telephone in the residence in which defendant Cummings lived in Durham and for the telephone in the residence in which Oldham lived in Chatham County. The records corroborated Oldham’s testimony and were competent for this purpose. They were properly admitted. 1 Stansbury’s, supra, § 155, p. 521. This assignment of error is without merit and is overruled.
Under defendants’ assignments of error to the instructions given to the jury by the trial judge they made eight arguments:
[5] 1. Defendants argue that the court did' not adequately define reasonable doubt. They rely upon State v. Hammonds, 241 N.C. 226, 85 S.E. 2d 133 (1954). In Hammonds it was held that, absent a request, the trial judge is not required to define reasonable doubt. Hammonds also held that the law does not require any set formula in defining reasonable doubt. In Hammonds the opinion pointed out that there were many approved formulae. In the present case the trial judge defined reasonable doubt as follows:
“[A] reasonable doubt is a doubt based on reason and on common sense, arising out of some or all of the evidence that has been presented; or lack or insufficiency of the evidence, as the case may be.
Proof beyond a reasonable doubt is proof that fully satisfies or entirely convinces you of the defendant’s guilt.”
*551The foregoing definition comports with the approved examples pointed out in Hammonds, and it is an adequate and clear definition of reasonable doubt. This argument is without merit.
[6] 2. Defendants argue that the trial judge “did not adequately explain credibility” in his charge. The defendants filed thirteen numbered requests for jury instructions. They argue that they requested but the trial judge failed, in his summation of the evidence, to mention the numerous crimes Oldham admitted committing but for which he was not charged or convicted, and failed to mention Oldham’s admission to valium addiction or that he sometimes obtained valium by deception. Our reading of the charge to the jury discloses that the judge adequately summarized the testimony of Oldham upon these points as follows: “that he had been convicted of breaking and entering, safecracking and indecent exposure and he has participated in other breakings and enterings since he was fifteen years old. He has participated in about 100 breaking and enterings and has entered about fifty safes. He has participated in a robbery, murder of Mr. and Mrs. Lee in Johnston County. . . .” Further as follows: “That he took valium and drank vodka and he secured valium by taking a pill bottle to the drugstore and he secured it from two drugstores. . . . That he was a valium addict for about two years before 1977; that he took up to eight pills daily and drank vodka. . . .” The trial judge is not required to give his instructions in the wording arranged by counsel. It is sufficient if he instructs in substantial conformity with the requested instruction. State v. Kirby, 3 N.C. App. 43, 163 S.E. 2d 911 (1968). The instructions upon this request by defendants was in substantial conformity with the request and was adequate. This argument is without merit.
Defendants further argue that the trial judge failed to inform the jury adequately of the grant of immunity to the State’s witness Oldham. We disagree. The trial judge instructed as follows: “Ladies and gentlemen of the jury the Court earlier in this trial instructed you that David Oldham, Jr. was testifying under a grant of immunity in this trial. Again, the Court instructs you that if you find that this witness testified in whole or in part for these reasons or this reason, you should examine his testimony with great care and caution in deciding whether or not to believe it.” Further in the charge the judge instructed: “He has *552been granted immunity from the Holland crimes and others about which he testifies and he has been promised he would serve his time in the county jail for his testimony in this trial. . . This argument of defendants is without merit.
From a reading of defendants’ argument it appears they object to the failure of the trial judge to argue their case to the jury for them. This the trial judge is not required to do nor may he properly do.
[7] 3. The defendants argue that “the trial court committed prejudicial error in charging the jury on the right of the defendants not to testify.” The defendants requested an instruction on their rights not to testify. Again we point out that the trial judge is not required to give his instructions in the wording arranged by counsel. It is sufficient if the trial judge instructs in substantial conformance with the request. The instruction as given was correct, adequate and in substantial conformance with the request. See State v. Scott, 289 N.C. 712, 724, 224 S.E. 2d 185, 192 (1976). This argument of defendants is without merit.
4. Defendants argue that the trial judge expressed his opinion, in violation of G.S. 15A-1222 and 1232, that certain facts had been proved. Defendants point to three instances where they contend the trial judge expressed an opinion.
[8] First: Defendants contend that the trial judge expressed the opinion that a conspiracy had been proved. They extract from the charge these words: “Now we are involved at (sic) this issue ladies and gentlemen of the jury, with a conspiracy.” Taken out of the context of what had been said immediately prior to the above extracted sentence and what was said immediately after the above extracted sentence the sentence might be suspect. However, the trial judge at this point was explaining to the jury the written issues that would be submitted to them. He then proceeded to define conspiracy and placed the burden upon the State to prove each element beyond a reasonable doubt. We cannot perceive how the jury could have understood the trial judge to be stating his opinion that a conspiracy had been established.
[9] Second: Defendants contend that the trial judge expressed an opinion that it had been proved that Oldham (State’s witness) was present at the robbery-murder of Mr. Holland. They extract *553the following words from the charge: “and also Oldham of course was there. . . The phrase extracted by defendants as an expression of opinion by the trial judge, when placed back in context, reads as follows:
“So, ladies and gentlemen of the jury, in connection with the second issue, Court charges that if you find from the evidence and beyond a reasonable doubt, that the defendants Logner, Cummings and Williams, and also Oldham of course was there, were present on the premises of Mr. Holland’s home on this day in question and they were at that time, as a result of a common purpose, to rob Mr. Holland with a firearm; that if one or more of them actually had a shotgun, pistols, a firearm; that they were aiding and abetting each other and that Mr. Holland was killed while the defendants were perpetrating armed robbery and that he died as a proximate result of the bullet wounds to his body received during the perpetration of an armed robbery; then you being so satisfied beyond a reasonable doubt would return a verdict of guilty of first degree murder as charged in the bills of indictment.”
It seems obvious that the trial judge was correctly requiring the jury to find that Oldham was present also.
[10] Third: Defendants contend that the trial judge expressed an opinion that it had been proved that a robbery had been committed. The sentence about which defendants complain appears in the trial judge’s explanation to the jury of the elements the State must prove beyond a reasonable doubt to justify convictions of kidnapping. When read in context, the instruction is: “[F]irst, that the defendants, while actually acting with a common purpose and aiding and abetting each other, unlawfully, that is without justification or excuse, restrained Mrs. Holland, that is restricted Mrs. Holland’s freedom of movement, by taping her legs, arms and mouth and eyes on 7 March 1977, in her own home in Wake County —members of the jury, the court may have erroneously in this charge referred to the date of this robbery 7 February. If so, strike that from your minds and substitute 7 March 1977 in all places. Secondly, that Mrs. Holland did not consent to this restrainment or confinement. . . .” The portion italicized is the portion to which defendants except. Obviously the trial judge was only seeking to eliminate confusion for the jury for he had in fact *554referred to “the 7th day of February 1977” in his instructions on the elements of armed robbery. We cannot conceive of the jury being led to think that the trial judge was of the opinion that the fact of a robbery had been proved.
In the three instances challenged by defendants we find no expression of an opinion by the trial judge.
5. Defendants argue that the trial judge did not accurately or properly explain conspiracy. We have carefully read the instruction about which defendants complain. Again, when placed back in context with the instructions immediately proceeding and immediately following the sentence extracted by defendants the instruction is a clear definition of a criminal conspiracy and adequately applies the law to the evidence in the case. This argument is without merit.
[11] 6. Defendants argue that the trial judge incorrectly instructed the jury that they could find the defendants guilty of armed robbery if the property stolen included deceased’s pistol. They concede there was evidence that defendants took deceased’s pistol but they argue that since the bill of indictment only charged the stealing of money it was improper to include the pistol in the instructions. The- fallacy in defendants’ argument is that in fact the error in mentioning the pistol, if error it be, was beneficial to defendants because it required the State to prove more than was required under the indictment. The trial judge instructed as follows: “. . . and that they took and carried away this money and a pistol from the person of Mr. Holland, without Mr. Holland’s voluntary consent, by endangering or threatening his life, Mr. Holland’s life, with the use or threatened use of the firearm, defendants knowing that they were not entitled to take this money and this pistol and intending at that time to deprive Mr. Holland of its use permanently, it would be your duty to return a verdict of guilty of robbery with a firearm.” As pointed out above, this coupling of the money and the pistol in the instructions required the State to prove more than should have been required of it. We find no prejudice to defendants.
7. Defendants argue that the trial court did not accurately or properly explain kidnapping.
8. Defendants argue that, as a whole, the trial court’s instructions were confusing and too favorable to the State.
*555It would constitute a laborious and unjustified writing and would seriously expand this already somewhat unnecessarily, voluminous opinion to articulate and answer each of defendants’ arguments under these two subheads. Suffice to say we have examined and considered each of defendants’ arguments hereunder and find them to be tediously tenacious but without merit. The instructions to the jury fairly and adequately apprised it of its duties and fairly and adequately applied the law to the evidence in the case.
For the reasons heretofore stated we hold that defendants’ assignment of error charging that the trial court failed to instruct the jury in accordance with defendants’ requests for instructions, and defendant Cummings’ assignment of error charging that the trial court should have granted his motion for mistrial and for a severance of his trial from the trials of Logner and Williams, are without merit.
In our opinion defendants received a fair trial free from prejudicial error.
No error.
