One possible outcome of the event of
getting two heads or two tails
in an experiment involving a sequence of
two flips of a fair coin
is the ordered pair
\[\begin{equation*}
(\mathrm{H}, \mathrm{H}),
\end{equation*}
\]
| where | \(\mathrm{H}\) | is a symbol denoting “heads” |
| \(\mathrm{T}\) | is a symbol denoting “tails”. |
