How to Use the Permutation Calculator?

The procedure to use the permutation calculator is as follows:

Step 1: Enter the value of n and r in the respective input field

Step 2: Now click the button  “Solve” to get the permutation

Step 3: Finally, the permutation will be displayed in the output field

What is Meant by Permutation?

In Mathematics, the permutation is defined as the possible number of arrangements of objects in a definite order. Here, the ordering of objects is important. In permutations, one should concern both the arrangement and the selection. It can be classified into three different categories, such as

  1. Permutation of n different objects
  2. Permutation when the objects are not distinct
  3. Permutation with repetition of objects

Thus, the formula to calculate permutations is given as follows:

Permutation, P(n. r) = n! /(n-r)!
