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' I-).
Round your answer to 2 decimal places
P(V'|-) =
