Entry 21 – Lesson Objective We will use a computer simulation to find experimental probabilities of complex compound probabilitiesHOW WILL I BE ASSESSED?Quiz Friday with at least one of the problems from today on it EXACTLY AS IS HW tonight with 3 problems, at least 1 of which will also be on Friday’s quizChapter test where I will have to simplify algebraic expressions
Entry 22 - Word WallWhen the mathematics becomes too complicated to figure out the theoretical probability of certain events, statisticians often use computer simulations instead.

DURING OPEN DISCUSSION… I contribute my ideas to class discussion. I listen to others when they are speaking. I wait for the appropriate time to contribute my ideas.I am polite in my interactions with other students and the teacher.
Entry 23 – Problem 5-34 RANDOM NUMBER GENERATORImagine a random number generator that produces numbers from 1 to 20. In each game below, if the stated outcome happens, Player X wins. If it does not, then Player Y wins.Game 1: A prime number = Player X wins Game 2: An even number = Player X wins Game 3: A number not divisible by three = Player X wins
Problem 5-34 continue… A. In each case, what is the theoretical probability that Player X wins? That Player Y wins? Decide whether each game above is fair. B. In which of the three games is Player X most likely to win? Why? C. In Game 1, the prime number game, if you play 40 times, how many times would you expect Player X to win? What if you played 50 times?

ENTRY 24 - CLASS DATA
ENTRY 24 - CLASS DATA rand(1,20,10)Obtain a random number generator from your teacher and set it up to generate integers from 1 to 20. Play the prime number game (Game 1) ten times. Start by deciding who will be Player X and who will be Player Y. Record who wins each time you play.

Entry 25 – Compare and ContrastHow did the experimental and theoretical probabilities of Player X’s winning from Entry 17 part (a) and Entry 18 compare?

Entry 26 – Problem 5-35 Janelle is going to babysit her nephew all day five times this summer. She had the idea that one way to entertain him is to walk to McBurger’s for a Kids Meal for lunch each time. The Kids Meal comes packed randomly with one of three possible action figures. Janelle would like to know the probability that they get all three figures in five trips. P(Nephew get all three figures in 5 trips) =randInt(1 , 3, 5)
Problem 5-35 continue… A. Call the action figures #1, #2, and #3. Use the random number generator to simulate five trips to McBurger’s. Did you get all three action figures?B. Simulate another five trips to McBurger’s. Did you get all three action figures this time? Yes No
Problem 5-35 continue… B. Do the simulation at least 20 times (that is, 20 sets of 5 random numbers), keeping track of how many times you got all three action figures in five tries, and how many times you did not. C. Use your results to estimate the probability of getting all three action figures in 5 trips. Should Janelle be worried? Yes No
