TASK: 52 Card Pickup

LAUNCH: Hand a standard deck of cards to each group. Allow students to read the directions for the task, and then allow each group to answer each of the questions. Use this video to introduce when appropriate. http://www.khanacademy.org/math/probability/v/probability-with-playing-cards-and-venn-diagrams

EXPLORE: 1. A card is randomly selected from a standard deck of 52 cards. What is the probability of either a face card or a 10? Use a Venn diagram to find your answer. 2. A card is randomly selected from a standard deck of 52 cards. What is the probability of a face card or a spade? Use a Venn diagram to find your answer.

DISCUSS: 1. How can a Venn diagram help you choose how you will find your answers in #1 and #2? 2. What does the overlap in the Venn diagram in #2 show? 3. How are the procedures in finding your answers to #1 and #2 different? What makes them different? 4. Which of the two Venn diagrams would you consider independent, why?

SOLIDIFY UNDERSTANDING LESSON:
 * Two events are overlapping if they have one or more outcomes in common.
 * Two events are disjoint if they have no outcomes in common.
