The probability that Tom makes a free throw is 0.91. Suppose he gets 12 free throws during a game. Find the probability that he makes: a. exactly 3 free throws b. at least one free throw c. between 8 and 11 free throws d. either 8 or 9 free throws e. at most 3 free throws f. an even number of free throws g. What is the expected value and standard deviation of the number of free throws he will make?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
