binomcdf(
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. 0p1 must
be true. numtrials must be an integer > 0. If you do not specify x, a list of
cumulative probabilities is returned.
