Binomial Distribution

To get to the binomial commands:

• Press
• Press or until choice binompdf or binomcdf is found

binompdf(n,p,r)

This command computes the probability of exactly r successes out of n trials where the probability of success of an individual trial is p.

The screen shows the probability of getting 4 successes out of 10 trial with the probability of success being 0.35

binomcdf(n,p,r)

This command computes the probability of at most r successes out of n trials where the probability of success of an individual trial is p.

The screen shows the probability of getting at most 4 successes(0, 1, 2, 3, or 4 successes) out of 10 trial with the probability of success being 0.35
