We are examining the price of a European put option on a share of stock GG with one period to expiration. No dividend is expected prior to expiration. The current stock price is $130, the exercise price is $135, the risk-free rate is 4%. The stock price of the next period is either $175.5 or $84.5.

1.. Using the replicating portfolio approach, what is the value of the put option?

2.. What is the risk-neutral probability of the upstate?

3. What is the risk-neutral probability of the downstate?

Someone, please help me with these questions!!:(
