Suppose I have 6 shirts, 4 ties, and 3 pairs of pants. If an outfit requires a shirt and pants, and can either have a tie or not have a tie, how many outfits can I make?

1) 6 shirts x 3 pants x No ties = 18 outfits without a tie.
2) 6 shirts x 3 pants x 4 ties = 72 outfits with tie
Total outfits =18 + 72 = 90 - with and without tie.
