For reference, I have added theorem

Theorem 26 (Theorem of de Moivre - Laplace) Let X1, X2, ... be independent random variables with Bernoulli(p)
distribution. Let
S, = > X;.
Then
Sn -
пр
< a
= ¤(a),
lim P
for every a E R.
(Vmp(1 – p)
51
In particular, when n is large (as a rule of thumb, when n > 30), then the cdf of the rescaled binomial random variable
Sn is approximately equal to the cdf of a standard-normal random variable Z
N(0, 1), i.e.
Sn
пр
< a
~ P(Z < a) = ¢(a).
