    E

    12


    正确答案: A
    解析:
    You are given that the probability of guessing the correct answer to a certain test question is 1/3, so the probability of not guessing the correct answer is 1 - (x/12). Since the probability of NOT guessing the correct answer to this question is given as 2/3, 1-(x/12) = 2/3 or 1-(2/3) = x/12. So 1/3 = x/12. Hence, x = 4.
