Probability: Business Travelers and Golf
A) 40% of business travelers carry either a cell phone or a laptop computer (USA Today, September 12, 2000). For a sample of 15 business travelers, compute the probability that 3 of the travelers carry a cell phone or a laptop.
b) Through the week ending September 16, 2001, Tiger Woods was the leading money winner on the PGA Tour, with total earnings of $5,517,777. Of the top 10 money winners, 7 players used a Titleist brand golf ball (www.pgatour.com). Suppose that we randomly select 2 of the top 10 money winners. What is the probability that exactly one uses a Titleist golf ball?
