Just a question from Fitz that i have no idea how the book got its answer.

Q20.
A cartoon contains a dozen eggs three of which have a double yolk. if 3 eggs are required to make a cake, find the probability that the three eggs chosen have double yolks.

Answer is 1/84


i thought it was 3/12 x 2/11 x 1/10????

it's carton not cartoon.
The question was probably something along the lines

"find the probability that none of the three eggs chosen have double yolks."
