Tips given to taxi drivers form a substantial part of their income. They also serve as a loose metric of service quality that can be useful for taxi companies. An analysis of a large dataset shows that the tips given (as a percentage of taxi fares) are normally distributed with mean 18.7% and standard deviation 5.8%. Furthermore, tips received for different trips are independent from each other. Use this information to answer the following questions. A taxi driver just received a 15% tip. S/he plans to do five more trips for the day. What is the chance that at least three out of the five trips will receive tips over 15%? Answer choices:
