In probability puzzles where you know at least one of two items has a certain property, the probability that both items share that property is not always 50% as commonly assumed; for example, when two tokens each have an equal chance of being gold or silver, and you learn that at least one is gold, the probability that both are gold is actually 1/3, not 1/2, because the possible outcomes are (gold, gold), (gold, silver), and (silver, gold), with only one of these three equally likely scenarios having both tokens as gold.
