Question 894656: A section of an exam contains two multiple-choice questions, each with three answer choices (listed "A", "B", and "C"). Assuming the outcomes to be equally likely, find the probability (as a reduced fraction) that the second answer is either "B" or "C". [Hint: List all the outcomes of the sample space first.]

since the first question could be anything, it doesn't enter into the picture.
the second answer could be A or B or C
the probability of getting A is 1/3 and the probability of getting B is 1/3 and the probability of getting C is 1/3.
the probability of getting B or C would be equal to 2/3.
unless there's something i'm missing, that's your answer.
