68cm and standard deviation of 8.)
RanNorm# (8, 68, 5)
(Randomly produces the body lengths of five
infants in the above example, and displays
them in a list.)
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
RanBin# (n, p [,m])
• Omitting a value for
returns the specified number of random values in list form.
Example
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.)
