92. A doctor has decided to prescribe two new drugs to 200heart patients, as follows : 50 get drug A, 50 get drug B and 100 get both. DrugA reduces the probability of a heart attack by 35 percent, drug B reduced theprobability by 20 per cent, and the two drugs, when taken together, workindependently. The 200 patients were chosen so that each has an 80 per centchance of having a heart attack. If a randomly selected patient has a heartattack, what is the probability that the patient was given both drugs ?

The sales agent Parson works in three cities A, B and C. To avoid unnecessary travel, he stays all day in the same city and spends the night there, moving to another city the next day if he does not have enough work.
