Permutation: Combination: Permutation calculator Formula: P(n,r) = n! / (n - r)! Where: n: n elements (n > 0) r: r subset elements (0 < r <= n) Combination calculator Formula: C(n,r) = n! /(r! * (n - r)!) Where: n: n elements (n > 0) r: r subset elements ...
A permutation is where we find out the number of options or possibilities and order matters. The notation for permutation is nPr where n is the number of items taken r at a time. The formula is {eq}nPr=\dfrac{n!}{(n-1)!} {/eq}. W...
In most cases, there will be more possible permutations of objects in a set than combinations because each different order of the items is considered a different permutation. With combinations, the order is irrelevant, and elements in different orders are considered the same combination, hence the...
