Question
Consider a financial market consisting of a bank account So(t) and a stock S₁ (t) modelled on a
probability space (2, F, P) with the time indices t = 0, 1, 2, ..., T.
consider a one period financial market model with T = 1,
S = {w₁, W₂}, F is the collection of all events and P is a probability measure such that P({w₁}) >
0, P({₂}) > 0. Assume that So(0) = 1, S₁ (0) = d> 0 and
So(1,₂)= (1+r)
So(1, ₁) =
S₁(1, ₁) =
S₁ (1, ₂) =
where 0 < d <d₂. r> 0 is the interest rate.
Question:

d₂,
a) Write the payoff of the European call option with strike price K.
b) Assume d = 5, r = 0.2, d₁ = 3, d₂ = 8, K = 7. Find the price of the option.
