# Permutation Calculator

Arranging of the whole or part of a set of objects with paying attention to the order of the management is called as the Permutation. Permutations are described as distinct objects taken at a particular time. This below Permutation calculator provides you the permutations count with the known values of n and r. Permutations calculator nPr can provide you the result in a fraction of the seconds. User friendliness is the main advantage of nPr calculator.

#### Formula:

_{n}P_{r} = n! / ( n - r )!
**Where,**
_{n}P_{r} = Permutations
n = Number of sample points in set n
r = Number of sample points in each permutation
### Example:

Calculate the Permutations with the n = 20 and r = 5.

#### Solution:

Permutations _{20}P_{5} = 20! / ( 20 - 5 )!

= 20! / ( 15 )!

= 1860480
