Binomial Distribution

A binomial distribution is a probability distribution that describes the number of successes in a given number of independent trials.

The conditions needed for a binomial distribution are:

  • n independent trials
  • the probability of success for each trial is a constant, p
  • only 2 outcomes (success and failure)

Important Concepts for Binomial Distribution

  • If X takes binomial distribution, we write it as X~B(n,p)
  • Our graphic calculator (Ti-84) is designed to find P(X=x) and P(X≤x)
  • To find P(X=x), use binompdf
  • The formula booklet also provides information on how to find P(X=x) manually.
  • To find P(X≤x), use binomcdf
