Is the answer 2/3?
There are two drawers in each of three boxes that are identical in appearance. The first box contains a gold coin in each drawer, the second contains a silver in each drawer, but the third contains a gold in one drawer and a silver in the other. A box is selected, one of its drawers is opened and a gold coin is found. What is the probability that the other drawer too will have a gold coin?
