The J.R. Ryland Computer Company is considering a plant expansion to enable the company to begin production of a new computer product. The companys president must determine whether to make the expansion a medium- or large-scale project. Demand for the new product is uncertain, which for planning purposes may be low demand, medium demand, or high demand. The probability estimates for demand are 0.20, 0.70, and 0.10, respectively. Letting x and y indicate the annual profit in thousands of dollars, the firms planners developed the following profit forecasts for the medium- and large-scale expansion projects.

		Medium-Scale Expansion Profit			Large-Scale Expansion Profit
		x		f(x)	y		f(y)
Demand	Low	50		0.20	0		0.20
	Medium	150		0.70	100		0.70
	High	200		0.10	300		0.10
