TOC WWK Mutually Exclusive & Mutually Exclusive—two events are mutually exclusive if they CANNOT occur at the same time. NOT Mutually Exclusive—two events that CAN occur at the same time. Addition Rule of Probability—a way to find the probability that either or both of two events occurs. Addition Rule

Big Picture

Addition Rule of The Addition Rule of Probability is the focus of today’s lesson. This Rule works with the concept of Mutually Exclusive/NOT Mutually Exclusive. The relationship is crucial! Probability

Foldable

Extra Practice Circle which of the following are mutually exclusive. 1.Red card and a Heart 2.Ace and Diamond 3.Club and Spade 4.Number 2-10 and Black

Can a Jack and a 7 happen at the same time on the same card? ANSWER: NO, therefore it is Mutally Exclusive

Can a Heart and an Ace happen at the same time on the same card? Why is this necessary? ANSWER: YES, therefore it is NOT Mutally Exclusive

Do you see how there are TWO Ace’s of Hearts? We have to subtract ONE of them so there isn’t a DOUBLE.

Can a Heart and an Ace happen at the same time on the same card?
