Question

Rework problem 18 from section 4.3 of your text, involving the expected number of putts made in a golf tournament. Assume that the golfer makes 70 percent of putts when they are less than 10 feet and 30 percent of putts when they are 10 feet or longer. The golfer takes 27 putts from less than 10 feet and 74 putts from 10 feet or longer during the tournament.

How many putts can the golfer expect to make during the tournament?

Answer 1

Expected number of putts by the golfer = 27(0.70) + 74(0.30) = 41.1 $\approx$ 41

i.e. he can expect to make 41 putts during the tournament.
