A statistician evaluated the winning strategies of teams in the National Football League (NFL). He used actual NFL play-by-play data to approximate the probabilities associated with certain outcomes (e.g., running plays, short pass plays, and long pass plays). The table below shows the probability distribution for the yardage gained, X, on a running play. A negative gain represents a loss of yards on the play. Find the probability of losing yardage on a running play.
