randInt( lower , upper , #ofTrials )
Returns a list of random integers bound by the specified
integers, lower

integer ‚ 1 that specifies the number of integers
returned in the list.
A seed value stored to rand also affects randInt( .

randNorm( mean , stdDeviation , #ofTrials )
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:
[mean N3(stdDeviation), mean+3(stdDeviation)].
A seed value stored to rand also affects randNorm( .
