A European put option on a non-dividend-paying stock has 3 months to maturity. The exercise price is $15, the stock price is $15, the risk-free rate of interest is 5%, and the volatility is 20%.

1. Use the Monte Carlo simulation to evaluate the option. Consider 4 iterations and the corresponding random values of epsilon, where epsilon = (-0.2767, -1.1812, -0.1793, -0.5444,).

2. Using the information above, compute the expected stock price at the end of the second month.
