PYTHON CODE FOR- Suppose an insurance company is insuring against burglary that happens with probability 0.1. The customer's wealth will be 40,000 if his or her home was broken in, and 50,000 otherwise. The insurance company pays 10,000 if a burglary happens, and 0 otherwise. The insurance policy costs 1,000. Simulate the average payoff to the insurance company if it sells to 100, 1000, or 10000 customers. Plot the histogram on a figure.
