Problem 1. You observe that a stock is currently selling for $100. Somehow you know that the two possible values for the stock at time T are $80 and $130. You also observe that (1+r)T = 1.1. You don’t know the probabilities of the two states of the world occurring. Using the two-state approach, determine the value of a T period call option with an exercise price of $110.
Problem 2. Using the put-call parity theorem, determine the value of a T period put of the stock described in problem 1 with an exercise price of $110.
