Assume XYZ stock is currently at S = $100. After one period, the price will move to one of the following two values: [uS and dS], where [u = 1.2; d = 0.9].

(b) For a strike price of 100 for call, find the delta of the call. (c) For a strike of 100 for put, find the delta of the put. (d) Explain the difference between the call delta and the put delta with the answer you get
