Applied to people who have no HIV antibodies, one rapid test has a probability of 0.004 of producing a false-positive. (a) Is a clinic tests 200 people who are free of HIV antibodies, what is the probability that no false- positives will occur? (b) What is the probability that at least one of the 200 people in part (a) will receive a false-positive?
