<s>[INST] In a study, the probability of dying from a certain disease within a year among smokers is twice as much as the probability of dying from the same disease among non-smokers. If \(P(A)\) represents the probability of dying from the disease among smokers, and \(P(B)\) represents the probability of dying from the same disease among non-smokers, then \(P(A\cap B)=\)?[/INST]
