- I need help with question #2 please Homework reviewJ 2 Uncorrelated random variables are not necessarily independent, however. A special situation occurs in the case of jointly Gaussian random variables. For the Gaussian case, uncorrelated random variables are also independent. I donot understand thses sentence. Please explain it through an example.○ Let assume 6 balls, 3 white, 2 black and 1 red. Random experiment is selection of three balls with replacement. R.v. X denoted number of white balls and r.v. Y denotes number of red balls. O P(X=2, Y-2)= 0 O Probability of which events is zero? O P(X=1, Y=2) = Compute joint pmf of X and Y
