A regional manager visits local fast food franchises and evaluates the speed of the service. if the manager receives her meal within 45 seconds, the server is given a free movie-admission coupon. If it takes more than 45 seconds, the server receives nothing. Throughout the company's franchises, the probability is 0.60 that a meal will be served served within seconds. What is the expected number of coupons a counter employee will receive when serving the regional manager?
