Firm X-Normal Price Firm X-Offer Discount Firm Y- Normal Price Payoff of Firm X - 5 Payoff of Firm X 4 Payoff of Firm Y-6 Payoff of Firm Y = 12 Firm Y-Offer Discount Payoff of Firm X - 11 Payoff of Firm X-9 Payoff of Firm Y-3 Payoff of Firm Y = 10 Identify the Nash equilibrium and best total outcome in the matrix. Explain why best total outcome is unlikely to be achieved.
