Every 15 minutes an express train arrives and waits 4 minutes to pick up passengers. four minutes after the express train leaves, a local train arrives and waits 3 minutes to pick up passengers. if a passenger arrives at the station at a random time during the rush period, find the probability of each of the following.
1. the express train will be waiting at the station.
2. no train will be waiting at the station.
i think that the probability is out of 15, but i have other people telling me it's out of 26. which is right?

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
