Solve the problem.R and C play a game by each showing none, one, or two fingers. If each player shows the same number of fingers, R pays C a number equal to the total number of fingers shown. If the two players each show a different number of fingers, C pays R a number equal to the total number of fingers shown.(a) Give the payoff matrix.(b) Suppose R shows one finger 50% of the time and two fingers 50% of the time, and C always shows two fingers. Calculate the expected value for this strategy.
