A certain tennis player makes a successful first serve 63% of the time. Suppose the tennis player serves 70 times in a match. a) What's the mean and standard deviation of the number of good first serves expected? b) Determine if you can use a normal model to approximate the distribution of the number of good first serves. c) What's the probability she makes at least 54 first serves?
