[MIXED STRATEGY NASH EQUILIBRIUM] Consider the following game, where r > 0: se do tribute Firm 2 High Price Low Price bute Firm 1 High Price (140, 140) (20, 160) Low Price 90+x, 90-x) (50, 50) to nce distribute (a) For what values of c do both firms have a dominant strategy? What is the Nash equilibrium (or equilibria) in these cases? a's (b) For what values of a does only one firm have a dominant strategy? What is the Nash equilibrium (or equilibria) in these cases? (c) Let c = 30. Is there a mixed strategy Nash equilibrium in this game? If so, what is it
