Answer:

Step-by-step explanation:

You are going to roll two dice.

If you roll one die, then there are 6 possible outcomes: $1, 2, 3, 4, 5, 6$

If you roll two dice, then there are $6\times 6=36$ possible outcomes:

$\begin{array}{cccccc}1-1&1-2&1-3&1-4&1-5&1-6\\ \\2-1&2-2&2-3&2-4&2-5&2-6\\ \\3-1&3-2&3-3&3-4&3-5&3-6\\ \\4-1&4-2&4-3&4-4&4-5&4-6\\ \\5-1&5-2&5-3&5-4&5-5&5-6\\ \\6-1&6-2&6-3&6-4&6-5&6-6\end{array}$
