Final answer:
The total number of all possible outcomes when 5 coins are tossed and 5 dice are rolled is 497,664.
Step-by-step explanation:
When 5 coins are tossed and 5 dice are rolled, we can calculate the total number of possible outcomes by multiplying the number of outcomes for each event.
Since there are 2 possible outcomes (heads or tails) for each coin toss and 6 possible outcomes (1-6) for each dice roll, the total number of possible outcomes is 2^5 * 6^5 = 64 * 7776 = 497,664.
