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.
