Final answer:
The total number of possible outcomes for each trial when rolling five standard six-sided dice is 7776.
Step-by-step explanation:
The total number of possible outcomes when rolling five standard six-sided dice can be calculated by raising the number of possible outcomes for one die to the power of the number of dice being rolled. Since each die has 6 faces, and there are 5 dice, the number of possible outcomes is 6^5 or 7776. Regardless of how many times the dice are rolled, the number of possible outcomes for each trial remains the same.
