Lightning-Induced Fatalities. As reported in an issue of Weatherwise, according to the National Oceanic and Atmospheric Administration, people at ballparks and playgrounds are in more danger of being struck by lightning than are those on golf courses. Of lightning-induced fatalities, 3.9% occur on golf courses. What is the probability that, of 250 randomly selected lightning-induced fatalities, the number occurring on golf courses is a. exactly 4? b. between 4 and 10, inclusive? c. at least 10? d. Comment on the accuracy of the normal approximation in this case.
