You are playing a treasure hunt card game that includes 8 treasure chests, 7 pirates and 9 islands. Each player is dealt 5 cards. Before seeing any of the cards, you randomly make a guess as to which treasure chest is hidden, which pirate buried the treasure and on which island the treasure was buried. What is the probability that you got all three correct before looking at your cards?
