A certain virus infects one in every 200 people. A test used to detect the virus in a person is positive 90% of the time when the person has the virus and 5% of the time when the person does not have the virus. (This 5% result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive."
