Find the saddle points and values of the payoff matrices. (To enter the saddle points, order your answers from smallest to largest r, then from smallest to largest c.) (a) 6 6 8 1 −2 −3 6 6 9 saddle points (r, c) = (r, c) = (r, c) = (r, c) = value (b) 5 7 5 8 1 6 1 11 5 9 5 10 saddle points (r, c) = (r, c) = (r, c) = (r, c) = value
