URGENT **********

Describe a practical problem where game theory and decision theory (specifically, solving decision trees) are both relevant. Comment on the interaction between game theory and decision theory, e.g. will decision theory be used before game theory or is it the other way? Will they be used once or multiple times? You do not have to give specific values of payoffs or probabilities and you do not have to identify all decisions and strategies. Your description should be detailed enough to just show why solving decision trees and finding equilibrium using techniques in game theory are both relevant to the problem and the order in which they are used.
