    Answer:

    1) 10.55%

    2) 30.77%

    Step-by-step explanation:

    52/52•39/51•26/50•13/49 = 0.105498… ≈ 10.55%

    100% chance you draw a unique card on the first draw

    51 cards left of which 13(3) = 39 are unique suit for your second draw

    50 cards left of which 13(2) = 26 are unique suit for your third draw

    49 cards left of which 13(1) = 13 are unique suit for your forth draw.

    Two balls are already green

    Leaves 4 red balls in a field of 13 balls

    4/13 = 0.307692… ≈ 30.77%
