1.1. Suppose random variable X is distributed as normal with mean 2 and standard deviation 3 and random variable Y with mean 0 and standard deviation 4, what is the probability density function (pdf) of X + Y. 1.2. Let X and Y be independent standard normal random variables. Determine the pdf of W = x² + y². Find the mean and the variance of U = W.
