Select the correct response. In an election, there are three candidates for governor from parties A, B, and C, three candidates for senator from parties A, B, and C, and four candidates for representative from parties A, B, C, and D on the ballot. Assume equal probabilities for selection of all candidates. The approximate probability of all candidates being selected from one party, A, is If party D drops from the representative race, then the approximate probability of all candidates being selected from one party is
