A certain virus infects one in every 500 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: find P(VI+). Round your answer to 2 decimal places. P(V+)= 80 b) Find the probability that a person does not have the virus given that they test negative: find P(V']-). Round your answer to 2 decimal places. P(V-) = 8​
