    Exclamation Probability with eggs

    A carton contains 12 eggs, 5 of which are cracked. If we randomly select 6 eggs for hard-boiling, what is the probability that two of the cracked eggs are selected?

    Or this one, i'm lost. Any help would be appreciated.

    hypergeometric since this is without replacement

    { {5\choose 2}{7\choose 4}\over {12\choose 6}} is the probability of EXACTLY 2 cracked and 4 non-cracked eggs.
