The hypergeometric distribution is generated when a sample of size n is taken, without replacement from a population containing a items of one type and b items of others.
\[p(x)=\frac{\left(\begin{matrix}a \\ x\end{matrix}\right)\left(\begin{matrix}b \\ n-x\end{matrix}\right)}{\left(\begin{matrix}a+b \\ n\end{matrix}\right)}\]
