Weekend HW!

This weekend, please complete the two AP problems provided in class (only one looks like an AP Problem). If you lost yours or you were absent, you can find them below. (We did not learn anything in class on Friday that is required to complete this homework!)

Here are some homework hints if you're stuck:

• For the first question ("Uncovering Expected Value"), remember that the probabilities given represent playing this game one time. The probability model that you have to complete is for the sum of the scores from your games if you play twice.
• To complete the probability model, you must first consider how you could get a sum of 0,1,2,3, or 4. Then, use this idea to find the probability.
• For example, to get a sum of 0, we would have to get "0 first and 0 second." This probability would be "0.4 x 0.4," which is .16. Use the same type of idea to complete the table. If you're stuck, think first in words, then numbers (just like when we started probability!
• For the second question, part (a) should be fairly straight forward. Part (c) deals with the median of a probability distribution; this is not something we would learn in class. It is your job to use the definition of median (provided in the question) to try to answer this question.
• Part (d) then brings back some of the ideas from the start of the year that address how the mean and median compare for different shapes of a distribution.
• And you can find the scoring rubric here: 2005 #2 Scoring Rubric
• And even though you skipped it, check out the answer to (b)!

 

Enjoy the weekend! One more full week before break! Woooooo!
