Chapter 7.4 - Counting Principle
The counting principle states that if one event has m possible outcomes and a second independent event has n possible outcomes, then there are m x n total outcomes for the two events together.
So, in the example below, if you have 2 pants and 3 shirts, you have 6 combinations.
But, there is an easier way than drawing a picture and counting the combinations.
In the example below, if you have 4 pants, 5 shirts and 3 shoes you would have 60 outfit combinations... and you didn't have to draw and picture and count to figure that out!
