l
Evaluate the following permutation
10P6
An order or arrangement
nPr = | n! |
(n - r)! |
where n is the number of items
r is the number of arrangements.
10P6 2 | 10! |
(10 - 6)! |
n! = n * (n - 1) * (n - 2) * .... * 2 * 1
n! = 10!
(n - r)! = (10 - 6)!
(10 - 6)! = 4!
10P6 = | 10 x 9 x 8 x 7 x 6 x 5 x 4! |
4! |
10P6 = | 10 x 9 x 8 x 7 x 6 x 5 x |
10P6 = 10 x 9 x 8 x 7 x 6 x 5
