Let X be a geometric random variable with parameter p = 1/3, and let Y be a Poisson random variable with parameter ? = 3. Assume X and Y independent. A rectangle is drawn with side lengths X and Y + 1. a. What is the expected value of the perimeter of the rectangle? Expectation = b. What is the expected value of the area of the rectangle? Expectation =
