1 On Desk: 1. Pencil 2. Math Journal 3. WDYE Learning Log 4. Parent Signatures? Learning Log: 1. HW: p.39, #11 (labsheet) #12, #28-31, #33-34 2.MSA Test Retakes – After school Today! 3. Quiz Tomorrow! Math CC7/8 – Be Prepared

2 Warm Up Collect any signed Paperwork? Lesson 2.4 Strategies for Theoretical Probability Begin HW? Tasks for Today

3 Warm Up Ice Cream FlavorNumber of People Who Prefer Vanilla10 Chocolate Chip Mint24 Oreo10 Chocolate Brownie Fudge6 50 students at Maywood Middle school were surveyed about their favorite ice cream flavor. The results are shown below. 1. What is the probability that a student’s favorite ice cream flavor is Oreo? Use proper notation! 2. What is the probability that a student’s favorite ice cream flavor is not Chocolate Brownie Fudge? Use proper notation! P(Oreo) = 10/50 = 1/5 P(not CBF) = 1 – P(CBF) = 1 – 6/50 = 44/50 = 22/25

7 What is a good strategy for finding all the possible color pairs? Make a tree diagram!!

8 Tree Diagram Choosing a block from 2 bags Start First Bag Second Bag OutcomeProbability R Y B R R R Y Y Y B B B RR R R YY Y Y Y Y R R B B B B B B KEY

9 The theoretical probability of each pair being chosen is 1/9. P (contestant will win the bonus prize) = 1/9

10 P (RR) = 1/9 Akimi only has a 1/9 chance of winning. P (BR or RB) = 2/9 Brelynn has a greater chance of winning

11 Yes, each contestant has a 1/9 chance of winning the bonus prize. No, it is not likely they will win. There is a greater chance of losing. P (winning) = 1/9 = 2/18 You would expect to win only 2 out the 18 times played. Begin HW – labsheet ACE#11
