en the current Center of Disease Analytics statistics, the probability of having the flu in our area is 10%.  A new flu test was just released with the following performance metrics.  In the case of a flu-infected person, the test comes back positive 90% of the time. For a non-flu infected person, the test comes back negative 95% of the time. If a person in our area tested negative, what is the probability that they have the flu?
