From a standard deck of 52 cards, 2 cards are drawn with out replacement.
How many combinations of 2 hearts are possible
would I say 13 C 2 to get 78 is this correct?
Also if a family has three kids what is the probability of having one boy?
i know the answer to be 3/8 I did this by writing out each set of possibilities, I was wondering if I am able to do a comb or perm to figure this out.
