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!

Can a Jack and a 7 happen at thesame time on the same card?
𝑷 (𝑨𝒐𝒓𝑩)=𝑷 (𝑨)+𝑷 (𝑩)ANSWER: NO, therefore it is Mutally Exclusive

Can a Heart and an Ace happenat the same time on the
𝑷 ( 𝑨𝒐𝒓𝑩 )=𝑷 ( 𝑨 )+𝑷 ( 𝑩)−𝑷 (𝒃𝒐𝒕𝒉)
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.
