Now you can apply the Binomial Theorem to binomial probabilities. To find the full probability distribution for a binomial experiment, expand the binomial open p plus q close to the n . .  For example, suppose you guess on four questions of a five-choice multiple-choice test. For four questions, n equals 4 comma  P(guessing correctly) = 1 fifth , comma  so p equals 0.2 comma  and q equals , 0.8.

  4 correct   3 correct   2 correct   1 correct   0 correct
open p plus q close to the fourth equals , 1 p to the fourth + 4 , p cubed , q + 6 , p squared , q squared + 4 p , q cubed + 1 , q to the fourth
  equals . open 0.2 close to the fourth + 4 . open 0.2 close cubed . open 0.8 close + 6 . open 0.2 close squared . open 0.8 close squared + 4 open 0.2 close . open 0.8 close cubed + open 0.8 close to the fourth
  = 0.0016 + 0.0256 + 0.1536 + 0.4096 + 0.4096

You can display the distribution of binomial probabilities as a graph.
