Given the price of oil and the volume of liquid in the drilling target, Extreme Drilling's revenue from a successful well is $16 million. Its drilling costs are $13 million. Enter the payoffs at the ends of the branches on the decision tree. Use Extreme Drilling's profit as its payoff. Ignore the potential costs of the seismic survey (that is, assume for now that the seismic survey costs are $0).

Let 0 = the well hits oil, W = the well hits water, \"0\" = the seismic survey reports oil, and \"W\" = the seismic survey reports water
