1.3 Probability (MOM) Progress s Score: 54.17/100 12/20 answered Question 17 A certain virus infects one in every 300 people. A test used to detect the virus in a person is positive 80% of the time if the person has the virus and 8% of the time if the person does not have the virus. (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 a percent rounded nearest fourth decimal place and do not include a percent sign. P(A | B)= b) Find the probability that a person does not have the virus given that they test negative, i.e. find P(A'| B'). Round your answer as a percent rounded to the nearest fourth decimal place and do not include a percent sign. P(A'IB') Question Help: Video 1 Video 2 Message instructor
