## What is ncr and npr

In maths, npr and ncr are two Probability functions that are represented Permutation and combination respectively.

In permutation npr and combination, ncr  n is the total number of objects and r is the sample size Where r <= n.

npr calculator is an online tool that is used to calculate a combination. You should have to give inputs n,r

Where,

n =  total number of object

r = objects from a group.

## What is the Permutation?

The number of ways of choosing a sample of “r” object from a group or a set of “n” distinct for selection of the project. In the case of permutation, the order matter, and replacement are allowed.

The number of distinct n object or set that taken r from that set at a time Is determined by the formula:

npr = n!/(n-r)!
