Suppose a random variable X has a CDF given by Fx (x) and similarly, a random variable Y has a CDF, Fy (y) . Prove that the function F(x,y) = Fx (x) Fy (y) satisfies all the properties required of joint CDFs and hence will ...a) Find the joint PGF for the pair of discrete random variables given in Exercise 5.13. b) From the result of part (a), find E [M] and E [N]. c) From the result of part (a), find E [MN]. In Exercise 5.13 Let and be jointly Gaussian random variables. Show that Z = aX + bY is also a Gaussian random variable. Hence, any linear transformation of two Gaussian random variables produces a Gaussian random variable. Suppose X and Y are independent and Gaussian with means of μX and μY, respectively, and equal variances of σ2. The polar variables are formed according to R =√ X2 + Y2 and θ = tan–1 (Y / X). - Find the joint PDF of ...Suppose In figure 5.7 and P i = 1/3, i = 1, 2, 3.
