Medicine and Clinical Studies In the movie A Christmas Story, Ralph "Ralphie" Parker wanted an official Red Ryder carbine-action 200-shot range model BB gun (with a compass in the stock). Everyone in the movie (including Santa) tells Ralphie he will shoot his eye out with this present. According to the Centers for Disease Control and Prevention, approximately 30,000 people visited an Emergency Room last year for BB gun accidents. The most common injuries were to the face, head, neck, and eye.23 In a survey of BB- and pellet gun-related injuries treated at hospitals, each injury was classified by primary body part injured and victim-shooter relationship. The results are given in the table below.

Suppose this table is representative of the entire population of BB- and pellet gun-related injuries, and a person seen in an Emergency Room suffering from this type of injury is selected at random.

a. What is the probability that the injury is to the eye and the shooter is a relative?

b. Suppose the injury was caused by a stranger. What is the probability that the body part injured is an extremity?

c. Suppose the injury is to the head/neck. What is the probability that the shooter is a friend/acquaintance?

d. Suppose the injury is not to the eye. What is the probability that the shooter is a relative?
