    Problem 1:

    4 eights + 4 fours

    8/52 = 2/13

    Problem 2:

    4 eights + 4 fours + 4 twos

    12/52 = 3/13

    Problem 3:

    4 aces + 13 diamonds - 1 ace of diamonds

    16/52 = 4/13

    8 or 4 is 8/52 or 4/26 or 2/13

    8 or 4 or 2 is 12/52 or 6/26 or 3/13

    ace or diamond is 26/52 or 1/2
