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.

randNorm(

[,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).
