Probability
Press %6 to access a menu of functions.
nPr Calculates the number of possible
permutations of n items taken r at a time.
The order of objects is important, as in a race.
nCr Calculates the number of possible
combinations of n items taken r at a time.
The order of objects is not important, as in a
hand of cards.
! The factorial of n is the product of the positive
integers from 1 to n. n must be a positive
whole number 69.
RAND Generates a random real number between 0
and 1. To control a sequence of random
numbers, store an integer (
seed value) ‚ 0 to
S E. The seed value changes randomly
every time a random number is generated.
RANDI Generates a random integer between two
integers, A and B, where A  RANDI  B.
Separate the two integers with a comma.
For nPr and nCr, enter the first argument, press
