randInt( (random integer) generates and displays a random
integer within a range specified by lower and upper integer
bounds. To generate a list of random numbers, specify an
integer >1 for numtrials (number of trials); if not specified, the
default is 1.
randInt(lower,upper[,numtrials])
randNorm( (random Normal) generates and displays a random
real number from a specified Normal distribution. Each
generated value could be any real number, but most will be
within the interval [mN3(s), m+3(s)]. To generate a list of
random numbers, specify an integer > 1 for numtrials (number
of trials); if not specified, the default is 1.

[,numtrials])
randBin( (random Binomial) generates and displays a random
integer from a specified Binomial distribution. numtrials
(number of trials) must be ‚ 1. prob (probability of success)
must be ‚ 0 and 1. To generate a list of random numbers,
specify an integer > 1 for numsimulations (number of
simulations); if not specified, the default is 1.
randBin(numtrials,prob[,numsimulations])
Note: The seed value stored to rand also affects randInt(,
randNorm(, and randBin( instructions (page 2-20).
