To find the probability that a Democrat opposes stronger drug control laws, we need to look at the intersection of the "Democrat" row and the "Opposes Stronger Drug Control Laws" column, which gives us a value of 43. We then divide this value by the total number of voters who oppose stronger drug control laws (110 + 43 = 153) to get 43/153 = 0.281 or 28.1%. However, the question is asking for the probability that a Democrat opposes stronger drug control laws, so we need to divide the value of 43 by the total number of Democrats (122) to get 43/122 = 0.352 or 35.2%. Therefore, the best choice is B.
