Autumn got a box of 24 assorted chocolates as a gift. The box contains 14 milk chocolates, 7 dark chocolates, and 3 toffees, but they are all individually wrapped so she doesn't know which candy is which kind. Dark Chocolate is Autumn's favorite. If she eats 2 candies today, what is the probability that... a) Both of the candies are dark chocolate? b) Neither of the candies are dark chocolate? c) At least one of the candies is dark chocolate? For all of the above, round to four decimal places
