THE CURRENT CLASSROOM “MODE”
Entry21– Lesson Objective
We will use a computer simulation to find experimental probabilities of complex compound probabilitiesHOWWILL I BE ASSESSED?Quiz Friday with at least one of the problems from today on it EXACTLY AS ISHW 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
Entry22- Word Wall
When the mathematics becomes too complicated to figure out the theoretical probability of certain events, statisticians often use computersimulationsinstead.
THE CURRENT CLASSROOM “MODE”
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.
Entry23– Problem 5-34RANDOM NUMBER GENERATOR
Imagine 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, thenPlayerY wins.Game 1:           A prime number = Player X winsGame 2:           An even number = Player X winsGame 3:           A number not divisible by three =PlayerX wins
Problem 5-34 continue…
A. Ineach case, what is the theoretical probability that Player X wins?  That Player Y wins?  Decide whether each game above is fair.B. Inwhich of the three games is Player X most likely to win?  Why?C. InGame 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?

ENTRY24- CLASS DATA
ENTRY24- 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) tentimes.Start by deciding who will be Player X and who will be Player Y.  Record who wins each time you play.

Entry25– Compare and Contrast
How did the experimental and theoretical probabilities of Player X’s winning fromEntry 17 part(a) andEntry 18compare?

Entry26– 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 toMcBurger’sfor 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 numbergeneratorto simulate five trips toMcBurger’s.  Did you get allthreeaction figures?B.Simulate another five trips toMcBurger’s.  Did you get all threeactionfigures this time?
Problem 5-35 continue…
B.Do the simulation at least 20 times (that is, 20 sets of 5 randomnumbers), keeping track of how many times you got all threeactionfigures in five tries, and how many times you did not.C. Useyour results to estimate the probability of getting all threeactionfigures in 5 trips.  Should Janelle be worried?

Entry27-Closure
How could Janelle get an even more accurate estimation of the probability?
Entry28:Homework Problems 5-38 through 5-42
