Evaluate the following permutation

6P5

Permutation Definition:

An order or arrangement

Permutation Formula:
nPr  =  n!
  (n - r)!

where n is the number of itemsr is the number of arrangements.

Plug in n = 6 and r = 5
6P5  2  6!
  (6 - 5)!
Factorial Formula:

n! = n * (n - 1) * (n - 2) * .... * 2 * 1

Calculate n!:

n! = 6!

6! = 6 x 5 x 4 x 3 x 2 x 1

6! = 720

Calculate (n - r)!:

(n - r)! = (6 - 5)!

(6 - 5)! = 1!

1! = 1

1! = 1

Calculate 6P5:
6P5  =  720
  1

6P5 = 720


Excel or Google Sheets formula:

=PERMUT(6,5)
