Let the spot price S = $100, strike K = $105 in one year, interest rate i = 3%, the standard deviation of continuously compounded interest is = 0:5 and assume a single binomial period model. Recall that a European option can only be exercised at the contract expiration. (a) What are ; B and the price for a European call? (b) What are ; B and the price for a European put? (Princing puts is the same as pricing calls with the exception being that the payoff for the put buyer is max(O; K - S) instead of max(O; S - K).
