Chapter 10, Problem 10(choose chapter or problem)
A local restaurant offers a free music CD with each Extraordinary Value Meal. Two different CDs are available, and you want both. There are equal numbers of the two CDs, and they are randomly distributed with each meal. a. Create the first few branches of a tree diagram showing the probabilities of getting two different CDs when you purchase Extraordinary Value Meals. End each path once it contains both CDs. b. This tree diagram can be extended indefinitely. (Its unlikely, but it might take 50 or more meals to get both CDs!) Use the pattern in the probabilities from 10a to help you calculate the expected number of Extraordinary Value Meals you will need to purchase to receive both CDs.
