(45 points) Consider a monthly binomial price process with u=1.10 and d=0.90 for some stock where the monthly interest rate is 5% and the initial stock price is $1000. The price of the share of stock goes up in each period with probability 60% and down with probability 40%. In all of the questions below, the time to expiration of any option is T=3 months and the strike price is K=$1000. Give your answers by contructing a binomial lattice or tree whenever necessary. a) (5 points) Determine the binomial stock process.
