Learn How to Calculate Circular Permutation - Tutorial


Circular permutation is the number of ways to place n distinct objects at the side of a fixed circle. This tutorial explains you how to calculate Circular permutation (Pn) from the given number of elements (n).


Circular Permutation (Pn) = (n-1)!

n = Number of distinct objects

Example :

How many distinguishable ways can 4 woman be seated around a circular table?

Given :

n = 4

To Find :

Circular Permutation (Pn)

Solution :

Pn = (n-1)! = (4-1)! = 3! = 1X2X3 The result is 6; therefore, woman can be seated in 6 ways around a circular table.
