Lesson 5: Fundamental Counting Principle Definition Fundamental Counting Principle uses multiplication to find the number of possible outcomes.

Lesson 5: Fundamental Counting Principle If an event M has m outcomes and event N has n outcomes then there are total of m x n outcomes Example: Coin is tossed and a Number Cube is rolled 2 x 6 = 12 outcomes

Lesson 5: Fundamental Counting Principle 1. Find the total outcomes when choosing helmets in three colors and two styles. 2. Find the total outcomes when rolling a Number Cube and choosing a letter from the word NUMBERS.

Lesson 5: Fundamental Counting Principle 2. Find the total outcomes when rolling a Number Cube and choosing a letter from the word NUMBERS. a. What is the probability of rolling a 6 and choosing the letter M? b. What is the probability of not rolling a 6 and choosing the letter M?
