a) Of the pure strategy equilibria you found for each of these games in PS1, which (if any) are inadmissible? b) Find all Nash equilibria in mixed strategies in the following 4 games. (By equilibria in mixed strategies, we mean equilibria in which at least one player plays more than one pure strategy with positive probability. None of the Nash equilibria you found in PS1 qualify!)
