Permutation is the number of ways a number of k objects can be selected from a set of n objects while giving relevance to the order selection.
The two ways of forming subsets from selecting a group of objects from a set are through combination and permutation. The act of selecting objects and arranging them into some kind of order is the process of permutation. On contrary, combination is the type of selecting objects wherein the order is not really important.
The selection process stated in this problem is permutation. Let P be the number of ways a k number of objects is chosen from a set of n objects.
For a permutation that allows repetition or replacement of the chosen object:
P= n*n*(k number of objects that will be selected)= [tex]n^{k}[/tex]
For a permutation that does not allow repetition or replacement of chosen object:
[tex]P = \frac{n!}{(n-k)!}[/tex]
Factorial is used to indicate the descending number of choices every time an object is selected. In order to select a k number of things, factorial n will be divided by the factorial of n-k.
