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.)
K6(g)3(PROB)4(RAND)4(Bin)
5,0.5)w
RanBin# (5, 0.5, 3)
(Performs the same coin toss sequence
described above three times and displays
the results in a list.)
K6(g)3(PROB)4(RAND)4(Bin)
5,0.5,3)w
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,
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.)
!*({)1,2,3,4,5,6,7,8
,9,10!/(})a!b(List)bw
K6(g)3(PROB)4(RAND)6(Samp)
!b(List)b,3,1)w
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.)
!*({)1,3,6,7!/(})a
!b(List)cw
K6(g)3(PROB)4(RAND)6(Samp)
!b(List)c,10)w
