(15) Consider the one-shot, simultaneous game below Player 2 Left right Player 1 Up 3, 2 6, 5 down 5, 6 2, 3 a) (4) Identify the Nash equilibria of this game and briefly explain why one of them is a Nash equilibrium.Suppose now that this game is sequential, and player 1 moves first. b) (3) Sketch the game tree for this game. Consider the following pair of strategies for this sequential game: {player 1 plays up, player 2 plays \"always play right\"}. c) (4) Explain why this pair of strategies is a Nash equilibrium to this game. d) (4) Is this pair of strategies a subgame perfect Nash equilibrium for this game? Explain why or why not
