1. Consider the following discrete time one-period market model. The savings account is given by Bo 1 and B1 1.1. The stock price is given by So 1 and S,-ξ where ξ is a random variable taking two possible values u 1.2 and d = 0.9. Consider a put option whose payoff at time l is P = (1-S)+.

4. Let X and Y be independent exponential random variables with pa- rameter ? 1. Given that X and Y are independent, their joint pdf is given by the product of the individual pdfs of X and Y, that is, fxy(x,y) = fx(x)fy(y) The joint pdf is defined over the same set of r-values and y-values that the individual pdfs were defined for. Using this information, calculate P(X - Y < t) where you can assume t is a positive...

Let X and Y be independent exponential random variables with pa- rameter ? = 1. Given that X and Y are independent, their joint pdf is given by the product of the individual pdfs of X and Y , that is, fX,Y(x, y) = fX(x) fY(y). The joint pdf is defined over the same set of x-values and y-values that the individual pdfs were defined for. Using this information, calculate P (X ? Y ? 2) where you can assume...
