\( \definecolor{colordef}{RGB}{249,49,84} \definecolor{colorprop}{RGB}{18,102,241} \)
The table below shows the possible outcomes when selecting two letters at random from the word "MAT" with replacement (after choosing a letter, it is put back before the next selection).
\(\begin{aligned} & \textcolor{colorprop}{\text{letter 2}} \\ \textcolor{colordef}{\text{letter 1}} \end{aligned} \) \(\textcolor{colorprop}{M}\) \(\textcolor{colorprop}{A}\) \(\textcolor{colorprop}{T}\)
\(\textcolor{colordef}{M}\) \(\textcolor{colordef}{M}\textcolor{colorprop}{M}\) \(\textcolor{colordef}{M}\textcolor{colorprop}{A}\) \(\textcolor{colordef}{M}\textcolor{colorprop}{T}\)
\(\textcolor{colordef}{A}\) \(\textcolor{colordef}{A}\textcolor{colorprop}{M}\) \(\textcolor{colordef}{A}\textcolor{colorprop}{A}\) \(\textcolor{colordef}{A}\textcolor{colorprop}{T}\)
\(\textcolor{colordef}{T}\) \(\textcolor{colordef}{T}\textcolor{colorprop}{M}\) ? \(\textcolor{colordef}{T}\textcolor{colorprop}{T}\)
Find the missing outcome.
