# Math Help - Distribution of the variate Y

1. ## Distribution of the variate Y

It X is binomially distributed with parameters n and p , what can you say about the distribution of variate
$
Y_n = \frac{X-np}{\sqrt{npq}} \; \; as \qquad n \to \infty
$

Have you heard of the normal approximation to the binomial distribution?
