Consider the following discrete time one-period market model. The savings account is given by Po and Si 1 and B11.1. The stock price is given by So-1 where is a random variable taking two possible values u-1.2 and 0.9. Consider a put option whose payoff at time 1 is P (1- Si)+. (a) Find a replicating strategy for this option. By considering the value of the d replicating strategy, find the time 0 price of the put option Po (b) Find the price Po using a second method via the Equivalent Martingale Measure (EMM).
