3.2 Use an area model. In the model, the large
squares represent wholes, the small rectangles
along the right and lower edges represent tenths,
and the small squares at the lower right represent
hundredths. The model is 3 and 2 tenths units long,
and 2 and 1 tenth unit wide.

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
