\subsection{\bf Gaussian Distribution---I}
\begin{itemize}
\item (b) Another important example is

\begin{equation}
p(x) = \frac{1}{\sqrt{2\pi} \sigma} \exp \left\lbrack - \frac{1}{2}
\frac{(x-\mu)^2}{\sigma^2} \right\rbrack
\end{equation}

\item This is the probability density of the normal or Gaussian
distribution---so called because it was first discussed by de Moivre in
1733.
