A golfer playing a new course encounters a hole that requires a drive of 145 yards to successfully clear a pond. She knows that her drives are normally distrib- uted with a mean of 155 yards and a standard devia- tion of 9 yards. What is the probability that after her drive her golf ball will be at the bottom of the pond?
P ( -2.81 < z < 0 )
