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 p m
RanBin# (

• Omitting a value for
returns the specified number of random values in list form.
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.)
u Random Extraction of List Data Elements (RanSamp#)
This function randomly extracts elements from list data and returns the results in list format.
RanSamp# (List X,
List X ... Any list data (List 1 to List 26, Ans, {list format data}, sub-name)
n
... Number of tries (When
1 < n < 999.)

... = 1 or 0 (When
element can be extracted multiple times.)
m
• = 0 is used when the
List 1 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
RanSamp# (List 1, 3, 1)
(Randomly extracts three elements from
List 1 and displays the result on the ListAns
screen.)
List 2 = {1, 3, 6, 7}
RanSamp# (List 2, 10)
(Randomly extracts 10 elements from List
2 and displays the result on the ListAns
screen. Elements are extracted repeatedly.)
