Abstract. This paper gives an improved binomial distribution with parameters $n$ and $p$ to approximate the Pólya distribution with parameters $N$, $m$, $r$ and $c$, where $p=1-q=\frac{r}{N}$. The improved approximation is more accurate than the binomial approximation when $N$ is sufficiently large.
