options:
%†
displays a menu with the following options:
Examples
<
!
A
factorial
is the product of the positive integers
from 1 to
n
.
n
must be a positive whole number
{
69.
nCr
Calculates the number of possible
combinations
of
n
items taken
r
at a time, given
n
and
r
. 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
. The order of
objects is important, as in a race.
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 2 integers,
A
and
B
, where
A
{
randint
{
B
. Separate the 2
integers with a comma.
