Suppose Edison and Hilary are playing a game in which both must simultaneously choose the action Left or Right. The payoff matrix that follows shows the payoff each person will earn as a function of both of their choices. For example, the lower-right cell shows that if Edison chooses Right and Hilary chooses Right, Edison will receive a payoff of 4 and Hilary will receive a payoff of 6. Hilary Left RightEdison Left 4, 4 6, 3Right 5, 4 5, 3The only dominant strategy in this game is for to choose .The outcome reflecting the unique Nash equilibrium in this game is as follows: Edison chooses and Hilary chooses.

Employees at a library check out books to patrons. books have an isbn and a name. the library sometimes has multiple copies of the same book. books have one or more authors. a patron is an individual who has an active (non-expired) library card. for each library card, we store the person's first and last names and their address. for each employee, we store their employee id, current salary, first and last name and their address. we also store the employee id of their current manager. each time we check out a book to a patron we need to store the date of the transaction, the employee who checked out the book to the patron, and the library card of the patron. some employees have library cards. if an employee patron turns in a book late, the fine that they pay is a percentage of their salary. some employees are authors who have library cards—they are allowed to check out as many books as they like.
