A new cotton mill has opened in a nearby town, and they have decided to offer an insurance contract to cotton farmers in the area.At the beginning of the season, farmers pay a premium of $480. If the weather is GOOD, the insurance will pay nothing to the farmer. If the weather is BAD, the insurance will pay an indemnity payment of $1600 to the farmer. Think that cotton mill's insurance agents have perfect information about the farmer's activity choice (means they can enforce a contract that requires the farmer to choose cotton).

1. What is the cotton mill's expected profit from this contract?
2. What are the expected utilities for planting cotton with insurance for Kelly and Xinda?
3. If Kelly is now choosing between planting cotton without insurance, planting rice, and planting cotton with insurance, what will she choose?
4. If Xinda is now choosing between planting cotton without insurance, planting rice, and planting cotton with insurance, what will she choose?
