Permutation & Combination Calculator — math calculators and step-by-step solvers
The Permutation & Combination Calculator computes the number of ways to select r items from a set of n items, either with order mattering (permutations) or with order ignored (combinations). Choose a mode to get P(n,r), C(n,r), or both at once. Use it for probability problems, scheduling, and counti
