text: you are trying to find the probability that democrats win, and the bill passes.  Let A be the event that the demos win, and B be the event that the bill passes.  Also recognize that this is a conditional probability question.\nWe know the following info:  \nP(A) = .6   "democrats have a 60 %"\nP(B|A) = .9 "90 % chance of passing if the Democrats win "\nP(A and B)  "what the question wants you to find"\nthe conditional prob formula says that \n\nP(A and B) = P(A) x P(B|A) = .9 x .6 = .54\n\nSo there is a 54% of both things happening
