A doctor has decided to prescribe two new drugs to 200 heart patients as follows: 50 get
drug A, 50 get drug B, and 100 get both. The 200 patients were chosen so that each had an
80 percent chance of having a heart attack if given neither drug. Drug A reduces the prob-
ability of a heart attack by 35 percent, drug B reduces the probability by 20 percent, and
the two drugs, when taken together, work independently. If a randomly selected patient
in the program has a heart attack, what is the probability that the patient was given both
drugs?​
