\begin{slide}
\begin{itemize}
\item Accept-Reject is sometimes an important technique in event
generation.

\item Suppose we generate a set $N$ of events $i$ with weight $w_i$
representing the production probability.  

\item Then if we want to calculate some simple quantity $q_i$, the
canonical method is to take
\begin{equation}
\langle Q\rangle = \frac{{\displaystyle\sum^N_{i=1}} q_i 
w_i}{{\displaystyle\sum^N_{i=1}} w_i}
\end{equation}
\end{itemize}
