Assume that of all the employees in a particular metropolitan area, 70% work full- time, 40% commute (to work) more than 30 miles, and 35% both work full-time and commute more than 30 miles. An employee in the metropolitan area is to be selected at random. What is the probability that the employee neither works full-time nor commutes more than 30 miles? 70% 50% 35% 25%
