rand
rand (random number) generates and returns one or more random
numbers > 0 and < 1. To generate a list of random-numbers, specify an
integer > 1 for numtrials (number of trials). The default for numtrials is 1.
rand[(numtrials)]
Tip: To generate random numbers beyond the range of 0 to 1, you can include
rand in an expression. For example, rand5 generates a random number > 0 and
< 5.
