Exercise 9

Avg difficulty 2.5

Okay, so we have the probabilities of our four swimmers Ben, Chad, Grover, and Tim each winning the heat at .1, .2, .4, and .3, respectively. Now suppose Ben, Chad, and Grover are UMW athletes, Tim is from Marymount, Ben and Tim are juniors, and Chad and Grover are sophomores. We'll define UU={Ben,Chad,Grover}, MM={Tim}, JJ={Ben,Tim}, and SS={Chad,Grover}. What's Pr(UU)?
