Apair of dice is rolled, and the number that appears uppermost on each die is observed. refer to this experiment and find the probability of the given event. (enter your answer as a fraction.) one die shows a 5, and the other is a number less than 4.

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
