Probability is a measure of how likely an event is to occur. Match one of the probabilities that follow with each statement of likelihood given.

A certain virus infects one in every 400 people. A test used to detect the virus in a person is positive 90% of the time if the person has the virus and 5% of the time if the person does not have the virus. (This 5% 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 answer to 4 decimal places. 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^c|B^c) =
