Suppose that Stock XYZ is currently trading at $80 and does not pay any dividends. Using a Cox-Ross-Rubinstein binomial tree with two periods, we would like to price a European down and out put option written on this stock with a strike price of $85, barrier level of $75. Assume that the binomial tree parameters are: u= 1.07, and e-rat = 0.99. Find the price of the barrier option. 1.21 3.88 4.98 6.33
