l
Evaluate the following permutation
6P2
An order or arrangement
nPr = | n! |
(n - r)! |
where n is the number of items
r is the number of arrangements.
6P2 2 | 6! |
(6 - 2)! |
n! = n * (n - 1) * (n - 2) * .... * 2 * 1
n! = 6!
(n - r)! = (6 - 2)!
(6 - 2)! = 4!
6P2 = | 6 x 5 x 4! |
4! |
6P2 = | 6 x 5 x |
6P2 = 6 x 5
