For anyone not convinced by the combinatorial argument that the
correct answer is 2/3, consider a scenario where each cabinet has
100 drawers.  One cabinet has all silver coins, one has all gold
coins, and one has 99 silver coins and 1 gold coin.  You pull a
drawer at random and find a gold coin.  What is the probability
that all the other drawers in the same cabinet have gold coins?
100/101.
