A Covid-19 diagnostic test made in China is 75% accurate on those persons who are infected and 80% accurate on those who are not. If 15% of the population of a particular city is infected and these tests are administered to almost everybody, compute the probability that a particular individual is infected, given that the test indicates that the individual has Covid-19. If the city has a million people, would you pay $38 million to test the whole population?

A diagnostic test is being developed to diagnose a new virus that has infected 10% of the world's population. If a person is infected with the virus, the probability that the diagnostic test comes back positive is 0.9 and if a person is not infected with the virus, the probability that the diagnostic test comes back positive is 0.25. Suppose a randomly seleted person is given the diagnostic test. Given that the test came back negative, find the probability that...

The players will also have to take a test like Test B above. But, there won’t be a follow up test. Any player that tests positive will have a mandatory 2-week quarantine. Given the probabilities that a positive test means the player has COVID-19: (3-4 sentences each)...
