A game is played with one standard die. On a turn, if a player rolls a 1, he gets two more rolls. If he rolls a 2, he gets one more roll. If he rolls anything else, his turn ends. His score is the sum of all the rolls on his turn (up to 3 rolls). If a player scores 5 points on a turn, what is the probability that it took 2 rolls?
