Evaluate the following permutation

8P6

Permutation Definition:

An order or arrangement

Permutation Formula:

nPr =	n!
	(n - r)!

where n is the number of items
r is the number of arrangements.

Plug in n = 8 and r = 6

8P6 2	8!
	(8 - 6)!

Factorial Formula:

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

Calculate n!:

n! = 8!

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

8! = 40,320

Calculate (n - r)!:

(n - r)! = (8 - 6)!

(8 - 6)! = 2!

2! = 2 x 1

2! = 2

Calculate 8P6:

8P6 =	40,320
	2

8P6 = 20,160

Excel or Google Sheets formula:

=PERMUT(8,6)

What is the Answer?

8P6 = 20,160

How does the Permutations and Combinations Calculator work?

Free Permutations and Combinations Calculator - Calculates the following:
Number of permutation(s) of n items arranged in r ways = nPr
Number of combination(s) of n items arranged in r unique ways = nCr including subsets of sets
This calculator has 2 inputs.

What 2 formulas are used for the Permutations and Combinations Calculator?

nPr=n!/r!
nCr=n!/r!(n-r)!
