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.

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 [
mN
3(
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.

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.
