Given below is a bivariate distribution for the random variables x and y. a. Compute the expected value and the variance for x and y. E(x)=E(y)=Var(x)=Var(y)= b. Develop a probability distribution for x+y (to 2 decimals). x+y17050100f(x+y) c. Using the result of part (b), compute E(x+y) and Var(x+y). E(x+y)=Var(x+y)=
