The owner of a firm must hire a manager to launch a new product. The new product can be successful and generate a revenue of 5000 or fail and generate a revenue of 1000. The probability of succ
success is 0.7 (and hence the probability of failure is 0.3). If the manager exerts low effort (e=e,) then the probability of success is 0.2 (and hence the probability of failure is 0.8). The manager's utility

- Managers of the restaurant, NicePizzeria@Nola, have to plan for the number of pizzas they want to make at the beginning of each day. Based on market research, the managers know the daily demand can only be one of the three levels: 30, 40 or 50 pizzas. Also, the probabilities of getting a daily demand of 30, 40, 50 pizzas are 0.3, 0.4, 0.3 respectively. The managers decide that their tentative daily supply of pizza should also be one of the three levels: 30, 40 or 50 pizzas. Each pizza costs $3 to make and the price is $8 per pizza. Note: The profit for each pizza sold is $5. For the ones supplied but not sold, the profit is -$3.
