An old lady is looking for help crossing the street. Only one person is needed to help her; more are okay but no better than one. You and I are the two people in the vicinity who can help; we have to choose simultaneously whether to do so. Each of us will get pleasure worth a 3 from her success (no matter n'ho helps her). But each one who goes to help will bear a cost of1, this being the r-alue of our time taken up in helping. set this up as a game. Write the paYoff table, and find all pure-strategy Nash equilibria.
