## Combination ncr Calculator

^{n}c_{r} = n!/(r!*(n-r)!)

## What is ^{n}c_{r }and ^{n}p_{r}

In maths, ^{n}p_{r} and ^{n}c_{r} are two Probability functions that are represented Permutation and combination respectively.

In permutation ^{n}p_{r} and combination, ^{n}c_{r} n is the total number of objects and r is the sample size Where r <= n.

^{n}c_{r} 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 combination?

The number of ways of choosing a sample of “* r*” object from a group or a set of “

*” distinct for selection of the project. In the case of combination, the order does not matter, and replacement are not allowed.*

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

^{n}c_{r} = n!/(r!*(n-r)!)

### How to calculate ^{n}c_{r} in maths?

You can use our online ncr calculator for fast calculation for you can just simply follow The below steps:

1.Use formula

^{n}c_{r} = n!/(r!*(n-r)!)

Where,

n = total number of object

r = objects from a group

2. calculate the factorial using the formula

3. subtract n from r than do factorial of that obtained result

4.Put the all calculated factorial values in the formula.
