Consider a subtraction game with subtraction setS={1,4}starting with 6 chips. Player I goes first, and if Player I is the last to remove a chip, then Player II pays one dollar to Player I; if Player II is the last to remove a chip, then Player I pays one dollar to Player II.

(a) Find the payoff matrix for this game.

(b) Find V+ and V- (Maximin and Minmaxi)

For (a), is below the correct payoff matrix? and how do I do (b)

Player 1 chips (0,4) (1,2)

Player 2 dollar (2,1) (1.4)
