nPr (number of permutations, MATH PRB, item 2) returns the
number of permutations of items taken number at a time.
items and number must be nonnegative integers. Both items
and number can be lists.
nCr (number of combinations, MATH PRB, item 3) returns the
number of combinations of items taken number at a time.
items and number must be nonnegative integers. Both items
and number can be lists.
items nPr number
items nCr number
! (factorial, MATH PRB, item 4) returns the factorial of a
positive integer or list of integers between 0 and 69.
value!
RANDINT( (random integer, MATH PRB, item 5) generates a
random integer within a specified range. It requires two
arguments: the lower and upper boundaries of the range (in
any order). Both arguments must be integers. Both arguments
can be negative. Both arguments can be lists.
