### Pre-Algebra

Fundamental Counting Principle

• I CAN use the fundamental counting principle to find the total number of outcomes.

• The fundamental counting principle is useful because it give another way to find the sample space of various real world events.

• They are also useful in finding the probabilities of various events.

• Fundamental Counting Principle—If an event M can occur in m ways and is followed by event N that can occur in n ways, then the event M followed by N can occur in m x n ways.

• You multiply the number of ways each event can happen.
