Today’s Agenda  1. Bell Ringer/Return Tests  2. Introduction to Probability  3. Fundamental Counting Principle  4. Permutations

Where is Probability?

Expressing Probability We will start here!

Fundamental Counting Principle  If one event has “m” possible outcomes and a second event has “n” possible outcomes, then there are m*n total possible outcomes for the two events together.

Permutations  A way of expressing the total number of outcomes from a set or number of things that can be ordered or arranged.
