G Suppose that X is a random variable with associated PMF of f where 1 1,2,3,...,34,35 ( ) 665 0 1,2,3,...,34,35 x x f x x          Find the expected value of X. Give your answer as a fraction in reduced form (i. e. A/B where A and B do not share any common factors). Hint: We saw the sum of the first n positive integers, but you will need to look up the formula for the sum of the squares of the first n positive integers.
