[Q: 21-4051928] Binomial Model. A stock is currently priced at $84.73 per share. The stock price will either increase or decrease by 25% over the next year. A call option on the stock has an exercise price of $72.17 and has one year until expiration. The risk-free rate is 3.4%. Part A: Calculate the two potential stock prices one year from today. Stock price if it increases: $ per share. (Round your answer to two decimal places and use the rounded value in Part B). Stock price if it decreases: $ per share. (Round your answer to two decimal places and use the rounded value in Part B). Part B: Calculate the two potential payoffs for the call option at expiration. Payoff if stock price increases: $ per share. (Round your answer to two decimal places and use the rounded value in Part C). Payoff if stock price decreases: $ per share. (Round your answer to two decimal places and use the rounded value in Part C). Part C: Use risk-neutral pricing to determine the probability that the stock price will increase. Probability of a stock price increase: \%. (Round your answer to two decimal places and use the rounded value in Part D). Part D: Calculate the call option premium using the binomial model. C: $ (Round your answer to two decimal places)
