Question:

(Chebyshev’s Inequality). (i) Show that, for any real-valued random variable X and any constants a > 0 and c, E(X − c)

2 ≥ a2 P{|X − c| ≥ a} .

(ii). Hence, if Xn is any sequence of random variables and c is a constant such that E(Xn − c)

2 → 0, then Xn → c in probability. Give a counterexample to show the converse is false.
