6. Let X have a uniform distributions are in range 1,2,....n. P(X=k) =1/n: k = 1,2,3...n. Find a formula for E(X) and V(X). Note: This came out as a function of n. 7. Roll a balanced 6 faced die once than observe the # X of dots turning up, than toas a balanced coin X time and observe the # of heads Y that occurs find the expected values of E(x) and V(X). generate a table
