Question: 1 let x and y be two independent random variables...

Question details

1. Let X and Y be two independent random variables following beta distributions Beta (120, 2019). (a) whats P(X=0.3)? (b) Whats E(2X -Y)? (c) Whats P(2X 4> 3Y)? d) Whats P(X< Y)? (e) Now if X and Y are no longer independent to each other Will the answers to (a)-(d) remain the same? Explain (f) Now define Beta(2019,120). Compare the median of X and Z, which one is bigger Compare the variance of X and Z, which one is biggr? Explain (Hint: no calculation is needed)
