\subsection{\bf Bernoulli Trials---I}

\begin{slide}
\begin{itemize}
\item A series of Bernoulli Trials is the generalized coin tossing
problem.

\item We have a sequence of independent ``trials''---each of which has
only two outcomes:

\begin{description}
\item{$\bullet$} Success or ``heads'':\ \ probability $p$
\item{$\bullet$} Failure or ``tails'':\ \ probability $q$
\end{description}
where, of course $p+q=1$.  

\item Afficiando's of affirmative action and
women's lib will note that generations of math books have downgraded
tails compared to heads.  

\item Anyhow, we follow in their footsteps and set
$b(k,n,p)$ as the probability of $k$ successes in $n$ trials.  
\end{itemize}
