When two dice are rolled, each die has six possible outcomes: 1, 2, 3, 4, 5, or 6. To find the total number of all possible outcomes, we multiply the number of outcomes for each die together since the outcomes of each die are independent of each other.
Therefore, the total number of all possible outcomes when two dice are rolled is 6 multiplied by 6, which equals 36.
So, there are 36 possible outcomes when two dice are rolled.
