Wednesday HW

Tonight please complete the "Uncovering Expected Value" worksheet provided in class (or below).
  • This assignment gets us thinking about how we might develop a casino game and determine what to charge people and/or what prizes we might assign!
  • The hardest part may be calculating the probabilities for the probability model (#1)....
    • Remember, we are going to play a game twice...
    • Each time we play the game we can earn 0, 1 or 2 points (in one play)
    • The "outcomes" in the table are the "sums," or how many points we earn (total) in the two games combined
    • Think: how could we have a sum of, say, 3? 
      • How many points would we get on the first play? And on the second?
      • Or, what's another way--what could we get on the first? And on the second?
  • Here are the correct probabilities for your model so you can check, and/or so you can use these to complete the rest of the assignment. 
    • (of course you have to figure out how to find all of these):
    • P(sum = 0): 0.16
    • P(sum = 1): 0.24
    • P(sum = 2): 0.33
    • P(sum = 3): 0.18
    • P(sum = 4): 0.09
  • For #5 you should get an expected value of $153 if you allot the prize amounts correctly
  • On the back:
    • These are the same sums from the front, so the probabilities are the same...
    • Now we want to think about making this a gambling game--your job is to decide which prize amount goes with which sum.....



    Tomorrow in class we'll move on to the second half of chapter 16--combining random variables! See you there!

    Here's the plan for the rest of the week (and what happened today):
    • Wednesday (12/12)
      • Stamp: Pinball Wizard
        • Practice finding expected value and standard deviation with calculator
        • Interpreting and using expected value
      • HW Questions
      • Classwork: Pinata Free Response (more practice!)
    • Thursday (12/13): Chapter 16 Notes/Examples: Combining Random Variables
    • Friday (12/14): Chapter 16 Notes/Examples: Combining Random Variables
    • Monday (12/17): Chapter 16 Wrap-Up Notes/Practice: Combining Random Variables
    • Tuesday (12/18): Chapter 14-16 Review, Questions, Practice
    • Wednesday (12/19): Chapter 14-16 Probability Test
    • Thursday (12/20): Chapter 14-16 Vocab Test (20 min), then Chapter 17 notes
    • Friday (12/21): More Chapter 17 Notes
    • There will be a take home assignment over break! It will either be....
