Discover the power of our Permutation and Combination Calculator. Quickly determine the number of possible arrangements (permutations) or selections (combinations) from a given set of items. Master nPr and nCr calculations for statistics, probability, and mathematical problems with ease.
Formula:
The calculator determines the number of permutations (arrangements) and combinations (selections) for a given set of items.
- Permutation Formula (nPr): P(n, r) = n! / (n-r)!
- Combination Formula (nCr): C(n, r) = n! / (r! * (n-r)!)
Where:
- n = Total number of items in the set.
- r = Number of items to choose from the set.
- ! = Factorial (e.g., 5! = 5 * 4 * 3 * 2 * 1).
