-λα = 4. We say that X is exponentially distributed with parameter 1>0 if the distribution function is given by P(X < x) = 1- e- a) Determine and plot the density function of X b) Calculate the expected value and variance of X c) Suppose that X1 and X2 are two independent, identically exponentially distributed with parameter 1. What is the distribution of random variable S, where S = X1 + X2? d) Calculate the mean and variance of S.
