randInt( lower , upper , #ofTrials
Returns a list of random integers bound by the specified
integers, lower  integer  upper. The #ofTrials is an
integer ‚ 1 that specifies the number of integers
returned in the list.
A seed value stored to
randInt( lower , upper )
Returns a single random integer.
randM( rows , columns )
Returns a rows × columns matrix filled with random
one-digit integers (L9 to 9).
randNorm( mean , stdDeviation
Returns a list of random numbers from a normal
distribution specified by mean and stdDeviation. The
#ofTrials is an integer ‚ 1 that specifies how many
numbers are returned. Each returned number could be
any real number, but most will be within the interval:
[meanN3(stdDeviation), mean+3(stdDeviation)].
A seed value stored to
randNorm( mean , stdDeviation
Returns a single random number.
