(a)    Show that if X is a nonnegative discrete random variable with E[X] = 0, then P(X = 0) = 1. (b) Repeat part (a) with E[X] = 1 for P(X = 1) = 1. Let X be Gaussian with parameters {μ = 0, σ}. (a) Find E[Y ] and the variance σ2 Y for Y = u(X), where u(·) is the unit-step function. (b) Repeat part (a) for Z = u(X − 1). Dec 08 2021 03:23 PM
