\section{Introduction}
\generic{Setup:}
Suppose we toss a 6-sided die $n$ times. \par
It is easy to detect the first time we roll a 6. \par
What should we do if we want to annouce the \textit{last}?
\problem{}<lastl>
Given $l \leq n$, what is the probability that the last $l$
tosses of this die contain exactly one six?
\vfill
\problem{}
For what value of $l$ is the probability in \ref{lastl} maximal?
\vfill
\problem{}
Finish your solution: \par
In $n$ rolls of a six-sided die, how do we (most reliably) detect the last time we roll a 6?
