Equations in Permutation and Combinations with Introduction of the Anekwe's Method of Swapping Factorials
Uchenna Okwudili Anekwe
Permutations and combinations is concerned with determining the number of different ways of arranging and selecting objects out of a given number of objects, without actually listing them. A permutation involves an arrangement of objects in a definite order while A Combinations On the other hand is not interested in arranging but only in selecting r objects from given n objects. A combination is a selection of some or all of a number of different objects where the order of selection is not important. In this Manuscript we are concerned about solving equations of permutation and combination, on how to determine n number of items and how it can be selected or arranged in r number of ways and also to introduce Anekwes method of swapping factorials in the case of determining r number of items.
