Let S = $65, K = $55, r = 7% (continuously compounded), d = 5%, s = 40%, T = 2, and n = 2. In this situation, the appropriate values of u and d are 1.52196 and 0.68386, respectively. What is the value of p*, the risk-neutral probability of an upward movement in the stock price at any node of the binomial tree?
