The LA Lakers play an 84 game season. They lost 3/7 of their games in the first half of the season and 5/14 of their games in the second half of the season. How many games did they lose?

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

Can you me find the missing length. i attached an image.
