David is concerned with setting a correct production level. He can produce 500 units or 1100 units. Regardless
of production, there is a 45% chance of high demand (2000 units) and a 35% chance of low demand (350 units) and a 20% chance of average demand (1000 units). Each unit costs $15 to produce and sells for $25. He can only sell the minimum of either demand or production (since he can't sell what he doesn't make and can't sell what isn't demanded).
