1. The problem statement, all variables and given/known data Hi, if you could offer help to any of these questions, it would be great, i was unable to attend my lectures this week and I had no idea how to do these. The joint pmf of x and y is p x,y = c(x^2 + y^2) x,y = 1,2,3 Find: a. c and the marginal pmfs of x and y b. e(x) c. the pmf of 3x-2y d. e(3x-2y) in two ways 2. Relevant equations 3. The attempt at a solution From first investigation, I think that I have to create a table with 1,1 1,2 1,3 2,1 2,2, 2,3 3,1 3,2 3,2 and x^2 + y^2 = 1 and the p = 1/9 since theres only 9 options. i have no idea how to continue.
