Unformatted text preview: . 9. What is the probability that there are no orders waiting? 5. Let X 1 and X 2 be two random variables. Find G = E [ max ( X 1 ,X 2 )] + E [ min ( X 1 ,X 2 )] . (1) 6. Two continuous random variables X and Y are described by the pdf f XY ( x,y ) = k, if | x || y | , | y | 1 , otherwise (2) where k is a constant. a) Find k . b) Are X and Y independent? c) Are X and Y uncorrelated? (Reminder: Two random variables X and Y are uncorrelated if E ( XY ) = E ( X ) E ( Y ))...
