4. Based on your data, what is the experimental probability that the family has two dogs or two cats? 5. If the family has three pets, what is the theoretical probability that they have three dogs or three cats?

6. How could you change the simulation to generate data for three pets?

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
