Enter the total number of objects and the sample size to calculate the number of possible permutations. A permutation is a group of items from a larger set in a specific, linear order. …

So, in Mathematics we use more precise language: When the order doesn't matter, it is a Combination. When the order does matter it is a Permutation.

The permutations formula used when 'r' things from 'n' things have to be arranged without repetitions is nothing but the nPr formula which we have already seen. i.e., n P r (or) P(n, r) = …
