 8. (10 points) Recall the random variable X in Question 3.

8. (10 points) Recall the random variable X in Question 3. Sx = [6, 3] and f(m) = 12/81 for a: E 3X- (a) (5 points} Using Chebyshev's Inequality, provide an upperbound to the probability 1 X P(X2 + 57 + 14 > 8.9375). (b) (5 points} Calculate this probability exactly and compare to the bound found in part (a). How.r informative is this bound
