Let c represent the event that a person has cancer. let d represent the event that a person is diagnosed with cancer. in a certain region of the country it is known from past experience that the probability of selecting an adult over 40 years of age with cancer is 0.08. the probability of a doctor correctly diagnosing a person with cancer as having the disease is p(d | c) = 0.84, and the probability of incorrectly diagnosing a person without cancer as having the disease is p(d | c 0 ) = 0.04. what is the probability that a person diagnosed as having cancer actually has the disease, i. e. find p(c | d)? round all values to 4 decimals, if needed.
