One wheel divided into eight sections, one red, two yellow, two blue and three green. What is the probability that yellow does not occur on either spin? I have the answer 28/64, and I only need to understand why the answer is that, the test is tmr and I still don’t understand, please reply if you could answer it, thank you.

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
