Question 1084889: Chris is choosing a 3-letter password from the letters A,B,C,D, and E. The password cannot have the same letter repeated in it. How many such passwords are possible? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Chris has 5 letters to choose from, with no repeats. But, it doesn't matter which order they are in. So he has: 5x4x3, or 60 different passwords to choose from. ☺☺☺☺
