A box contains 8 dark chocolates, 8 white chocolates, and 8 milk chocolates. I choose chocolates at random (yes, without replacement; I’m eating them). What is the chance that I have chosen 20 chocolates and still haven’t got all the dark ones?

    since there are 3 kinds of chocolate you get (5/6)*(1/3) which should give you your answer
