Binomial Probabilty Distribution Calculator

An online calculator to calculate the binomial probability distribution.

If in a given experiment the probability that event A occurs is p and the probability that it does not occur is 1 - p, then the probability that A occurs exactly k times in n trials is given by:

P = n
C k p k (1-p)n - k

The calculator below allows to calculate P for k = 1, 2,... ,n.

How to use the calculator

1 - Enter p and n and press "enter". p must be positive and smaller than 1. This calculaltor is limited to values of n equal to or smaller than 12.
