A club or a face card? Is this event a union or an intersection?

How can the Addition Rule help you?

The Addition Rule is P(A or B) = P(A) + P(B) − P(A and B).

Remember a union is the cards that can be found in both events, where the intersection is the card they have in common.P(club or face) = P(club) + P(face) − P(club and face)

Refer to the Math Notes box in Lesson 3.1.5 for more assistance.

Not a club and not a face card?

This question is asking for the complement of part (a).
