Here is just a general question. I've got a game theory question, which asks to solve a firm's decision problem. How do I define the decision problem? Is it an equation that equates the total probability of all the events to some outcomes?
A quick look on Wikipedia defines a decision problem (in complexity theory) as a question with a yes or no answer. http://en.wikipedia.org/wiki/Decision_problem Without more information, we can't help you with this question.
