A recent survey by the American Cancer Society has shown that the probability that someone is a smoker is P(S) = 0.39. It has also determined that the probability that someone has lung cancer, given that he or she is a smoker is P(LC|S) = 0.205. What is the probability (rounded to the nearest hundredth) that a random person is a smoker and has lung cancer P(S ∩ LC)?
