!
A
factorial
, n!, is the product of the positive
integers from 1 to
n
. The value of
n
must be a
positive whole number
{
69. When n = 0, n! = 1
nCr
Calculates the number of possible
combinations
given
n
and
r
, non-negative integers. The order of
objects is not important, as in a hand of cards.
nPr
Calculates the number of possible
permutations
of
n
items taken
r
at a time, given
n
and
r
, non-
negative integers. The order of objects is
important, as in a race.

displays a menu with the following options:
rand
Generates a random real number between 0 and
1. To control a sequence of random numbers, store
an integer (seed value)
|
0 to
rand
. The seed value
changes randomly every time a random number is
generated.
randint(
Generates a random integer between two
integers,
A
and
B
, where
A
{
randint
{
B
. The
arguments of the function are:
randint(
integerA
,
integerB
)
