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.
