A certain virus infects one in every 300 people. A test used to detect the virus in a person is positive 80% ofthe time if the person has the virus and 8% of the time if the person does not have the virus.Rounding your answer to four decimal places, find the probability that a personhas the virus given that they have tested postive 0.002 xdoes not have the virus given that they test negative 0.991 x
