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. 0  p  1 must
be true. numtrials must be an integer > 0. If you do not specify x , a list of
cumulative probabilities is returned.
