Determine whether the given procedure results in a binomial distribution. If not, state the reason why. Rolling a single die 47 times, keeping track of the "fives" rolled.

Not binomial: the trials are not independent.

Procedure results in a binomial distribution.

Not binomial: there are more than two outcomes for each trial.

Not binomial: there are too many trials.

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
