Multiple Choice
Use the fundamental counting principle to find the total number of outcomes (or outfits) if you have a suitcase with 5 different shirts, 3 types of jackets, 2 different pants, and 3 types of shoes.
13, because 5 + 3 + 2 + 3 = 13
120, because 5 x 4 x 3 x 2 =120
90, because 5 x 3 x 2 x 3 = 90
52, because (5 + 3 + 2 + 3) x 4 = 52
