u Random Integer Generation (RanInt#)
RanInt# generates random integers that fall between two specified integers.
RanInt# (A, B [,n]) A < B |A|,|B| < 1
E 10 B – A < 1 E 10 1 < n < 999
• A is the start value and B is the end value. Omitting a value for
n returns a generated random
number as-is. Specifying a value for
n returns the specified number of random values in list
form.
Example Operation
RanInt# (1, 5)
(Generates one random integer from 1 and
5.)
K6( g) 3(PROB) * 4(RAND) 2(Int)
1 ,5 )w
RanInt# (1, 10, 5)
(Generates five random integers from 1 to
10 and displays the result on the ListAns
screen.)
K6( g) 3(PROB) * 4(RAND) 2(Int)

u Random Number Generation in Accordance with Normal Distribution
(RanNorm#)
This function generates a 10-digit random number in accordance with normal distribution
based on a specified mean  and standard deviation  values.
RanNorm# (
 ,  [,n])  > 0 1 < n < 999
• Omitting a value for
n returns a generated random number as-is. Specifying a value for n
returns the specified number of random values in list form.
Example Operation
RanNorm# (8, 68)
(Randomly produces a body length value
obtained in accordance with the normal
distribution of a group of infants less than
one year old with a mean body length of
68cm and standard deviation of 8.)
K6( g) 3(PROB) * 4(RAND) 3(Norm)
8 ,68 )w
RanNorm# (8, 68, 5)
(Randomly produces the body lengths of five
infants in the above example, and displays
them in a list.)
K6( g) 3(PROB) * 4(RAND) 3(Norm)
