Please just one more help.. Audrey planned a gala to raise money for charities. The tickets to the gala were sold for
$175.00 each, and a total of 240 people attended the gala. Of those who attended, 5
represented the charities and were given free tickets. It cost $45.50 a person to produce
the gala. If the profits from the gala were split evenly between 2 charities, how much, in
dollars, was donated to each charity?

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
