## What is Combination Probability?

Combination Probability is the number of ways of selecting r items from a set of n. A combination is an unordered collection of unique elements. Given the set, n, of all possible unique elements, a combination is a subset of the elements of n. The order of the elements in a combination is not important. Additionally, the elements cannot be repeated in a combination (i.e., every element appears once); this is often referred to as "without replacement/repetition".

## How to Calculate Combination Probability?

Combination Probability calculator uses Combination Probability (nCr)=(n Set)!/((r Items)!*(n Set-r Items)!) to calculate the Combination Probability (nCr), Combination Probability is the number of ways of selecting r items from a set of n. Combination Probability (nCr) and is denoted by nCr symbol.

How to calculate Combination Probability using this online calculator? To use this online calculator for Combination Probability, enter n Set (n) and r Items (r) and hit the calculate button. Here is how the Combination Probability calculation can be explained with given input values -> 167960 = (20)!/((9)!*(20-9)!) .

### FAQ

What is Combination Probability?
Combination Probability is the number of ways of selecting r items from a set of n and is represented as nCr=(n)!/((r)!*(n-r)!) or Combination Probability (nCr)=(n Set)!/((r Items)!*(n Set-r Items)!) . n Set is the total number of the available sets from which items will be selected and r Items are the total items that can be selected from the available set.
How to calculate Combination Probability?
