u 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 .
RanBin# (n, p [,m]) 1 <
n < 100000 1 < m < 999 0 < p < 1
• 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
RanBin# (5, 0.5)
(Randomly produces the number of heads
that can be expected in accordance with
binomial distribution for five coin tosses
where the probability of heads is 0.5.)

RanBin# (5, 0.5, 3)
(Performs the same coin toss sequence
described above three times and displays
the results in a list.)
