The following examples illustrate the commutative property of multiplication. 5 · 2 · 9 = 2 · 5 · 9 study the examples, then choose the statement that best describes the property. a · b = a ÷ b a · (b · c) = (a · b) · c a · b = b · a a · b = a · c

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
