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.)

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,
n
[,
m
])
List X ... Any list data (List 1 to List 26, Ans, {list format data}, sub-name)
n
... Number of tries (When
m
= 1, the number of elements is 1
< n <
List X. When
m
= 0,
1
< n <
999.)
m
...
m
= 1 or 0 (When
m
= 1, each element is extracted only once. When
m
= 0, each
element can be extracted multiple times.)
•
m
= 0 is used when the
m
setting is omitted.
Example Operation
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.)
