Create a 3 period Binomial model on an American Put. Assume S0=$99, X=$100, r=0.50% (do not worry about Tjust assume the risk free return for each node is .5% (1.005)), u = 9.5% (1.095), d = -5.5% (.945), please give the value of an American PUT at each observation (there should be 10!)---but you need to WATCH FOR EARLY EXERCISE! to get this right. If the put is worth below its intrinsic value, you need to use the intrinsic value to calculate the value for the previous period.

Draw it please
