Suppose that spies are not available.

a) Given the payoff matrix above, solve for the mixed strategy for countries A and B. Let q denote the probability that country B bombs country A. Let p denote the probability that country A doesn't develop weapons of mass destruction. b) Explain what country A's mixed strategy means for country B's expectation concerning what B thinks A will do. c) Given A's mixed strategy, how does B's expected payoff from "bomb" compare to B's expected payoff from "do not bomb"? d) Given B's mixed strategy, how does A's expected payoff from "develop" compare to A's expected payoff from "do not develop?"
