1) There are 6 neckties, 4 shirts, and 3 pairs of pants in the closet. If I have to wear a shirt, necktie, and pants to work every day, how many days can I go to work without wearing the same outfit twice?

We choose 1 from 6 neckties, 1 from 4 shirts and 1 from 3 pants. The total possible outcomes are the product of each choice, i.e, 6*4*3 = 72
