Permutation (nPr) is the way of arranging the elements of a group or a set in an order. Combination (nCr) is the selection of elements from a group or a set, where order of the elements does not matter.

Is nPr greater than nCr?

Differences between Permutations and Combinations nPr is the formula to find permutations of n objects taking r at a time. nCr is the formula to find the unique permutations, otherwise known as combinations, of n objects taking r at a time. An order does not matter in combinations. Generally, NPR is greater than NCR.

What is the meaning of nCr and nPr?

Permutation: nPr represents the probability of selecting an ordered set of ‘r’ objects from a group of ‘n’ number of objects. nPr = n!/(n-r)! Combination: nCr represents the selection of objects from a group of objects where order of objects does not matter. nCr = n!/[r!.
