About Permutations & Combinations
The **Permutation and Combination Calculator** is a tool used in combinatorics and probability to figure out the number of ways a subset of items can be selected from a larger set. The key difference between the two is whether the order of selection matters. This tool instantly calculates both, helping you solve complex problems quickly.
How to Use the Calculator
- Enter the **Total number of items (n)**, which is the size of the entire set you are choosing from.
- Enter the **Number of items to choose (r)**, which is the size of the subset you are selecting.
The calculator will automatically display the results for both permutations (nPr) and combinations (nCr).
