Linus and Rerun share 300 dollar according to the following rule: each chooses one of the numbers, either 0, 1, 2, or 3. If the sum of their numbers is not greater than 3, then each receives the number he chose times 100 dollar. If the sum of their numbers is greater than 3, then both receive nothing and the 300 dollar is donated to a charity. 1. Formulate this situation as a normal form game. Represent their payoff by using a matrix. 2. Find all pure strategy Nash equilibria. 3. Find all mixed Nash equilibria.
