Consider a random variable Y with the following probability function: 0.1 ify = -1, f(y) : 0.5 ify = 1, 0.4 ify = 3, 0
Consider a random variable Y with the following probability function: 0.1 ify = -1, f(y) : 0.5 ify = 1, 0.4 ify = 3, 0 otherwise. (a) Find V(Y) using the formula V(Y) = E[(Y - E())2]. (b) Using the result of (a) only, find V(Y/2 + 1)
