Probability 400 There is a raffle at the end of the year in Mrs. Cox’s class. When a name is drawn, it is placed back into the box. There are three prizes – an iPod worth $150, $100 in cash, and an iPad worth $800. To help offset the price of these items, she charges $10 for a ticket (the rest of the money was donated). Each of Mrs. Cox’s students gets one ticket. She has 65 students. What is the expected value? Should you participate in the raffle? Back
