    P = 1/6 or 0.1667

    Step-by-step explanation:

    Let A, B and C be the three events and 1,2 and 3 be the three dates. The sample space for this problem is:

    {A1, B2, C3} {A1, B3, C2} {A2, B1, C3} {A2, B3, C1} {A3, B1, C2} {A3, B2, C1}

    There are six possible outcomes and since there is only one correct answer, the possibility of guessing all 3 questions right is:

    P = 1/6

    P = 0.1667
