l
Evaluate the following permutation
6P3
An order or arrangement
nPr = | n! |
(n - r)! |
where n is the number of items
r is the number of arrangements.
6P3 2 | 6! |
(6 - 3)! |
n! = n * (n - 1) * (n - 2) * .... * 2 * 1
n! = 6!
(n - r)! = (6 - 3)!
(6 - 3)! = 3!
6P3 = | 6 x 5 x 4 x 3! |
3! |
6P3 = | 6 x 5 x 4 x |
6P3 = 6 x 5 x 4
