Random Number Generation in Accordance with Binomial Distribution
(RanBin#)
This function generates random integers in accordance with binomial distribution based on
values specified for the number of trials
n
and probability
p
.

• Omitting a value for
m
returns a generated random number as-is. Specifying a value for
m
returns the specified number of random values in list form.
Example
Operation
