A new test for detecting a disease has been developed. Medical trials show that 92% o patients with the disease show a positive test result. If 4% of the population have the disease, determine the probability (to 3 decimal places) that:

a.) a radnomly selected person shows a positive result to the test.

b.) A person showing a positive result suffers from the disease.
