3. Consider the binomial asset pricing world. At time t 0, you have no cash and you own 4 put options, with strike price K 5 and which expire at time t 1. The stocks current price So 4, the "up factor" u 2, the "down factor" d 1/2, and the risk-free interest rate is r = 1A The risk-neutral price of each option is Vo = 1.20.
