Shirley Jean STEWART, Appellant,
v.
The STATE of Nevada, Respondent.
No. 9869.
Supreme Court of Nevada.
June 28, 1978.
Morgan D. Harris, Public Defender, and Kirk B. Lenhard, Deputy Public Defender, Las Vegas, for appellant.
Robert List, Atty. Gen., Carson City, George E. Holt, Dist. Atty., and H. Leon Simon, Chief Appellate Deputy Dist. Atty., Las Vegas, for respondent.

OPINION
PER CURIAM:
Convicted, by jury verdict, of attempted murder (NRS 200.010; NRS 208.070),[1] appellant here contends (1) the evidence was insufficient to sustain her conviction, and (2) she was denied a fair trial because of prosecutorial misconduct. We disagree.
1. Although defense witnesses testified that appellant had shot the victim in self defense, the jury chose to believe the prosecution witnesses' testimony that appellant had threatened the victim and then shot him without provocation. We have previously held that where "there is conflicting testimony presented, it is for the jury to determine what weight and credibility to give to the testimony." Hankins v. State, 91 Nev. 477, 538 P.2d 167, 168 (1975). Accord, Lloyd v. State, 94 Nev. 161, 576 P.2d 740 (1978); Porter v. State, 94 Nev. ___, 576 P.2d 275 (1978). Where, as here, there is substantial evidence to support the jury's verdict, it will not be disturbed on appeal. Cunningham v. State, 94 Nev. 128, 575 P.2d 936 (1978); Sanders v. State, 90 Nev. 433, 529 P.2d 206 (1974).
*474 2. Appellant argues she was denied a fair trial through improper questioning by the prosecutor. On direct examination, appellant testified that she had been convicted of felony manslaughter in 1970. On cross-examination, the prosecutor attempted to delve further into appellant's prior conviction. Before appellant had an opportunity to answer an allegedly improper question, her counsel objected and the objection was sustained. The prosecutor did not pursue the line of questioning. Under these circumstances, we fail to perceive either prejudice or reversible error. See State v. Worth, 217 Kan. 393, 537 P.2d 191 (1975); Lister v. State, 528 P.2d 1126 (Okl.Cr.App. 1974). Cf. Fairman v. State, 83 Nev. 287, 429 P.2d 63 (1967).
Affirmed.

"An act done with intent to commit a crime, and tending but failing to accomplish it, is an attempt to commit that crime...."
