Theorem 3.16: Let X~binomial(n,p) and . For fixed d>0, and, equivalently, . Note that the first probability approaches 0 as n increases without limit and the second quantity approaches 1 under the same circumstances. Proof of Theorem 3.16: By Chebyshev’s Theorem, . Note that in the statement of Chebyshev’s Theorem.

Here’s another proof: Set x=y=1 in the binomial theorem. (Brualdi, p. 129) C(n,0)-C(n,1)+C(n,2)+…(C(n,n) = 0 (if n(1) Check: 1-4+6-4+1=0. Check: 1-5+10-10+5-1=0. If n is odd, you can cancel terms two at a time; if n is odd, it’s not so easy to prove that the alternating sum is 0. Proof by induction: Left to you to fill in the details.
