Question 24 A certain virus infects one in every 500 people. A test used to detect the virus in a person is positive 90% of the time if the person has the virus and positive 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". Positive Negative Totals Virus 180 20 200 No virus 7984 91816 99800 Totals 8164 91836 100000 If you like to do calculations in Excel, click Download CSV to download csv file of data.

Round your answer to the nearest hundredth of a percent 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(AC| BC). Round your answer to the nearest hundredth of a percent and do not include a percent sign. P( AC | BC ) = % Check
