Consider two players, A and B, each of which can choose action X or Y. Their payoffs are represented in the following matrix, where K is a constant. Player A X Y X A: 15 B: 12 A: 20 B: 30 Player B Y A: 18 B: 24 A: 18 + K B: 22 Q2 a) First assume that K > 0. Does either player have a dominant strategy? If so, explain what it is and why.

equilibrium of this game.
Q2 c) Now assume that K<0. Do players have dominant strategies and what is the Nash
