Returns an integer matrix containing random elements that are
binomially distributed with number of independent Bernoulli
trials Ntrials, and with probability successProbability
of a single trial with success, where successProbability
is between 0 and 1.
The value rows is the number of rows and
cols is the number of columns in the result.
A binomially distributed variate represents the number of successes in
Ntrials independent Bernoulli trials with probability
of a single trial success successProbability.
