Problem 1. Let X be a normal random variable with mean 0 and variance 1 and let Y be uniform(0.1) with X and Y being independent. Let U-X + Y and V = X-Y. For this problem recall the density for a normal random variable is 2πσ2 (a) Find the joint distribution of U and V (b) Find the marginal distributions of U and V (c) Find Cov(U, V).
Imagine we have two independent uniform distributions, A and B. A ranges between −2 and −1, and is zero everywhere else. B ranges between +1 and +2, and is zero everywhere else. What are the mean and standard deviation of a portfolio that consists of 50% A and 50% B? What are the mean and standard deviation of a portfolio where the return is a 50/50 mixture distribution of A and B?
Let X and Y be independent random variables. Random variable X has a discrete uniform distribution over the set {1, 3} and Y has a discrete uniform distribution over the set {1, 2, 3}. Let V = X + Y and W = X − Y . (a) Find the PMFs for V and W. (b) Find mV and (c) Find E[V |W >0].
