Permutation is the act of putting all the members of a set into a sequence or order in mathematics. In other words, if the set is already sorted, the act of reordering its pieces is known as permuting. Permutations may be found in practically every branch of mathematics, at varying degrees of prominence. They frequently appear when alternative orderings on finite sets are examined. The permutation formula is as follows.

nPr = ((n!) )/((n-r)!)

nPr = ((50!) )/((50-5)!)

nPr = ((50!) )/((45)!)

nPr = ((50*49*48*47*46*45)!)/((45)!)

nPr = 11441304000/45

nPr = 254,251,200

Therefore, there are 254,251,200 ways to select these cases if order of selection matters.
