4. The symbols in this problem are as defined by the textbook for the binomial model with two steps, i.e., T = 2. This problem is about the option price of a European call option. See, for example, Exercise 6.5, p. 154. Data: S(0) = 120, X = 110, U = 0.3, D = -0.1, and R=0.1. (a) (7 pts) Find the expected payoff. (b) (7 ptsFind the price C#(0) of the option. 5. (20 pts) The symbols in this problem are as defined by the textbook for the binomial model. You are asked to find the price of a European call option where the exercise time T = 3 and a dividend div = 15 is paid at time I = 2. Data: S(0) = 120. X = 110, U = 0.2. D = -0.1 and R = 0.1 4.
