    1) A single contestant find all 3 daily doubles
    2) The returnnig champion gets all 3 daily doubles
    3) Each of the players selects precisly one of the daily doubles

    1 and 2) Let's say Moe is one of the contestants. The chance that he will get all 3 daily doubles is (1/3)^3.

    So the chance that any one of the three contestants will get all 3 is 3 x (1/3)^3.

    Thanks for your help! My instructor advised that part 1 is (1/3)^2; part 2 you were correct and 3) is (2/3)(1/3). They only response that makes sense, to me anyway, is no. 2.
