Game theory

Ken and Gerard are roommates for a weekend and have succeeded in making their living quarters cluttered in very little time. Both would prefer to be in an uncluttered room, and if they both help to clean up each gets a utility of five. If one cleans and the other does not, the one who does not gets a utility of eight while the one who cleans gets a utility of zero because he had to do all the work.
