Please work on problem sets 1, 3, 4, 5, 6, 7, 15, 25 and 26that can be found at the end of chapter 13 of Hull's textbook.

1A stock price is currently $40. It is known that at the end of one month it will be either $42 or $38. The risk-free interest rate is 8% per annum with continuous compounding. What is the value of a one-month European call option with a strike price of $39?

3What is meant by the delta of a stock option?

4 A stock price is currently $50. It is known that at the end of six months it will be either $45 or $55. The risk-free interest rate is 10% per annum with continuous compounding. What is the value of a six-month European put option with a strike price of $50?

5: A stock price is currently $100. Over each of the next two six-month periods it is expected to go up by 10% or down by 10%. The risk-free interest rate is 8% per annum with continuous compounding. What is the value of a one-year European call option with a strike price of $100?

6: For the situation considered in Problem 5 what is the value of a one-year European put option with a strike price of $100? Verify that the European call and European put prices satisfy put-call parity.

7: What are the formulas for u and d in terms of volatility?

15: Calculate u, d, and p when a binomial tree is constructed to value an option on a foreign currency. The tree step size is one month, the domestic interest rate is 5% per annum, the foreign interest rate is 8% per annum, and the volatility is 12% per annum.

25: Consider a European call option on a non-dividend-paying stock where the stock price is $40, the strike price is $40, the risk-free rate is 4% per annum, the volatility is 30% per annum, and the time to maturity is six months.a.Calculate u, d, and p for a two step treeb.Value the option using a two step tree.c. Verify that DerivaGem gives the same answerd. Use DerivaGem to value the option with 5, 50, 100, and 500 time steps.

26: Repeat Problem 25 for an American put option on a futures contract. The strike price and the futures price are $50, the risk-free rate is 10%, the time to maturity is six months, and the volatility is 40% per annum.
