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 within 45 seconds. What is the expected number of coupons a counter employee will receive when serving the regional manager?
Therefore expected number of coupens = 0.60+0=0.60
| probability | success to get coupens | |
| Meal will served withn 45 seconds | 0.60 | 1 | 0.60*1=0.60 |
| Meal will not served within 45 second | 1-0.60 | 0 | 0.40*0=0 |
