WebDec 3, 2006 · Counting Formula Fundamental Principles of Counting. If one thing can be done in r ways, a second thing in s ways, a third thing in t ways, etc., then the total number of ways all things can be done together is. r x s x t. Example: Barb has 5 shirts, 6 pants, and 3 pairs of shoes. How many ways can she get dressed? 5 x 6 x 3 = 90 ways. Permutation Webp= number of desired outcomes total number of possible outcomes (for equally likely outcomes) (2.1) Calculating a probability then simply reduces to a matter of counting the number of desired outcomes, along with the total number of outcomes. snl hip hop nativity
