TAs Tuan and Alex both really want to teach the conditional probability recitation, as it is their favorite topic in the course. They decide to play a game to decide which one will get to teach the recitation. Tuan and Alex each take a standard deck of cards. Independently, each of them selects a card uniformly at random from their respective decks. The TA who picks the card with the higher rank will teach the recitation. What is the probability that the rank of Tuan’s card is strictly higher than the rank of Alex’s card?
