Discrete random variables X and Y have the following joint probal bution f(x,y) | x-0 | x 1 y-0 0.1 0 y=1 | 0.1 | 0.1 y=2 | 0.1 | 0.2 y-310 10.4 (a) Compute the correlation coefficient pry (b) Compute the probability P(Y 2 2, X 0) (c) Compute the probability P(Y 2 2X 0). (d) If this is a game and you win (100X +10Y2) each time you play this game. What is the expected amount you win per game? 5. A random variable X has a mean μ = 12, a variance σ2-9, and an unknown probability distribution. Using Chebyshev's theorem, estimate (a) P(6< X < 18) (b) P(3< X<21)
