A company donates to charity every year as its contribution to society. If the company makes a profit in that year, 2/9 of the profit will be allocated for donations. If the company incurs a loss, the company will also allocate 0.05 of the loss for donations. If the company makes a profit of $43.2 million in a certain year and incurs a loss of $2.5 million and $6.5 million respectively in two consecutive years, calculate the total donations the company would have allocated for charity in those three years.​

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
