Parameters
Parameters 
Description 
x 
Function domain, integer, valid on closed interval [0,n]. 
N 
Defines number of trials. n must be a positive integer. 
p 
Defines success probability. p must lie on the [0,1] closed interval. 
Returns

the binomial cumulative distribution function (CDF).

Description

The binomial cumulative distribution function is defined by the following equation: 

 

where q=1-p and I is the discrete interval [0,1,...n] on which the binomial CDF is not zero. The result of BinomCDF is the probability of observing up to x successes in n independent trials and where the probability of success in any given trial is p.
