Question 1176920: One statistic used to assess professional golfers is driving accuracy, the percent of drives that land in the fairway. In 2012, driving accuracy for PGA Tour professionals ranged from about 45% to about 75%. Rory McIlroy, the highest winner on the PGA tour in 2012, only hits the fairway about 57% of the time. McIlroy is also one of the longest drivers on the tour, and increased distance is generally associated with decreased accuracy.
Assuming that a binomial distribution can be used, what is the expected number of fairways that McIlroy hits in a round in which he hits 17 drives?
