    Remember a union is the cards that can be found in both events, where the intersection is the card they have in common.

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

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

     intersection

  3. Not a club and not a face card?
