This is called Binomial Distribution, or Bernoulli trials, and I agree with the answer given by Ira.

Using the Binomial Distribution Commands on Ti-83 or 84:
Commands for binomial distributions (Bernoulli Trials), p = PROBABILITY OF SUCCESS, n TRIALS:
• binompdf (n, p) to produce the entire list of probabilities, x from 0 to n
• binomcdf (n, p, k) to get the (cumulative) probability of any x value from 0 to k.
