7 The current price of a financial asset that does not generate dividends is So= 100 EUR. We assume that the price of this asset evolves in time according to a binomial model with a 6-month period. At the end of each semester, the price of the asset is expected to increase by 10% or decrease by 10%. The risk free interest rate is r = 0.04 p.a. (simple interest). (a) Find the possible asset prices at maturity T = 1. (b) Calculate the present value of a European put with strike price K = 100 EUR at T = 1
