A health study tracked a group of people for five years. At the beginning of the study, 20% were classified as heavy smokers, 30% as light smokers, and 50% as nonsmokers. Results of the study showed that given a light smoker, the conditional probability that he/she died were twice as likely as the one given a nonsmoker, but only half as likely as the one given a heavy smoker during the five-year study. Given that a randomly selected participant from the study died over the five-year period, calculate the conditional probability that the participant was a heavy smoker. Round your answer to the 2nd decimal place. Non among the others 0.42 0.57 0.25 0.35 0.20
