(This 8% result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive". a) Find the probability that a person has the virus given that they have tested positive, i.e. find P(A B). Round your answer to the nearest tenth of a percent and do not include a percent sign.
