In Major League Baseball, excluding the wildcard round, a total of 8 teams participate in the postseason playoffs. Teams pair up each round to play against each other. The winner of each round goes on to play another winning team. In each round, the losing team is eliminated from the playoffs. Discuss the features of the graph that models the playoff scenario. Is the playoff graph a continuous or discrete graph? Explain.

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
