C. Hail Mary Shot - A Hail Mary shot is a shot thrown from a place far away from the basket. Since it is far, people say you need to pray or hail Mary to make it. Based on Piel's records, 2 out of 500 hail Mary shots made by all players in the league went in. To know the chances of Piel witnessing a hail Mary shot, distribution should be used with average rate of occurrence equal to With this, the probability that Piel will never witness a hail Mary shot in the game is
