A large population consists of two types of individuals: one always drives on the left (L), and the other always drives on the right (R). For the purposes of this question, assume that no other types can arise in the population. If two same types meet one another, they each get a payoff of 1, but if two different types meet one another, they each get a payoff of 0. Letr be the proportion of R types in the population. Answer the following questions: 1. (5 points) Find the fitness of the L type. 2. (5 points) Find the fitness of the R type. 3. (10 points) Find any evolutionary stable equilibria of the game. 4. (5 points) Is there any unstable equilibria? If yes, find it; if no, explain.
