A toy manufacturer has three different mechanisms that can be installed in a doll that it sells. The different mechanisms have three different setup costs $($overheads$)$ and variable costs and, therefore, the profit from the dolls is dependent on the volume of sales. The anticipated payoffs are as follows. Light Demand Moderate Demand Heavy Demand Probability $0\mathrm{.}350\mathrm{.}450\mathrm{.}20$ Wind$-$up action $$325,000$ $$190,000$ $$170,000$ Pneumatic action $$300,000$ $$420,000$ $$400,000$ Electrical action $-$$$400,000$ $$240,000$ $$800,000($a$)$ What is the EMV of each decision alternative?
