A

**factorial**is a function that multiplies a number by every number below it. For example 5!= 5*4*3*2*1=120.**What is a Factorial?**

- 2
**factorial**is 2! = 2 x 1 = 2. - 4
**factorial**is 4! = 4 x 3 x 2 x 1 = 24. - 5

## How do you calculate combinations?

**Combinations**are a way to

**calculate**the total outcomes of an event where order of the outcomes does not matter. To

**calculate combinations**, we will use the formula nCr = n! / r! * (n – r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.

## What is nPr formula?

Permutation:

**nPr**represents the probability of selecting an ordered set of ‘r’ objects from a group of ‘n’ number of objects. The order of objects matters in case of permutation. The**formula**to find**nPr**is given by:**nPr**= n!/(n-r)!## What is the formula for calculating permutations?

One could say that a

**permutation**is an ordered combination. The number of**permutations**of n objects taken r at a time is determined by the following**formula**: P(n,r)=n! (n−r)!## How many combinations of 1234 are there?
