Introduction to Topic 10.4 - Permutations and Combinations

When we calculate probability of an event, we need to know how many different outcomes are possible for the situation. For example, suppose you have 6 pairs of pants, 3 pairs of shoes, 7 pairs of socks, and 10 shirts. How many different outfits can you create? If you try to list them and then count, it is tedious to find all the possible combinations! In this topic, you will learn some rules for determining the number of outcomes for a set of events.

Essential question: How do we determine the total number of outcomes for a sequence of events?
