list of probabilities from 0 to
numtrials is returned. The probability density function (pdf) is:

binomcdf( computes a cumulative probability at x for the discrete binomial distribution
with the specified
numtrials and probability of success (p) on each trial. x can be a real
number or a list of real numbers. 0
p1 must be true. numtrials must be an integer > 0. If
you do not specify
x, a list of cumulative probabilities is returned.
