1.1. Create an Excel worksheet in which the user inputs S, Sd, Su, K, r and T. Check that the no-arbitrage condition (1.1) is satisfied. Compute the value of a call option in each of the following ways: (a) Compute the delta and use (1.2). (b) Compute the state prices and use (1.5a). (c) Compute the risk-neutral probabilities and use (1.6a). (d) Compute the probabilities using the stock as numeraire and use (1.8a). Verify that all of these methods produce the same answer. 1.1.
