    The condition "If the coin is a gold coin......" restricts the sampling to a subset of the 3 caskets. The subset is the two boxes that have at least one gold coin. The probability that the randomly selected casket with at least one gold coin has 3 gold coins is 1/2. Therefore the probability that the second coin in the casket is also gold is 1/2.
