Permutation Calculator is a free online tool that displays the possible number of arrangements of objects. CoolGyan’S online permutation calculator tool makes the calculation faster, and it displays the permutations in a fraction of seconds.
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
- Permutation of n different objects
- Permutation when the objects are not distinct
- Permutation with repetition of objects
Thus, the formula to calculate permutations is given as follows:
Permutation, P(n. r) = n! /(n-r)!
