Npr formula: Given two numbers

Given two numbers, n and r, the task is to compute nPr, which represents the number of ways to arrange r elements from a set of n elements. It is calculated using the formula n!/ (n−r)!, where "!" denotes the factorial operation. In combinatorics, nCr and nPr are essential formulas used to calculate combinations and permutations. They represent the number of ways to select and arrange objects from a set. nCr refers to combinations, where order does not matter, while nPr refers to permutations, where order does matter. Permutations (nPr) refer to the number of ways to arrange r objects out of n total objects, where the order of arrangement matters. Combinations (nCr), on the other hand, refer to the number of ways to select r objects from n objects without regard to the order of selection. Permutations formula can be used to find the different arrangements of alphabets, numbers, seating arrangements, and all other activities involving arrangements.
