Discussion Post: Permutation
Suppose we count a word as having 3 letters. How many "words" can be made from the 26 letters in the English alphabet?
We know that this is permutation (order matters) since "its" and "tis" are different words. Note the formula for permutations is n!(n-r)!n!(n-r)! using 'n' different things taken ‘r' at a time.
The response should include a reference list. Using one-inch margins, Times New Roman 12 pnt font, double-space and APA style of writing and citations.
