Final answer:
When tossing 8 coins, there are 256 different possible outcomes.
Step-by-step explanation:
When tossing a coin, each toss has two possible outcomes: heads or tails.
So, for one coin, there are 2 possible outcomes.
When tossing 8 coins, each coin has 2 possible outcomes, resulting in a total of 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 256 possible outcomes.
