Answer:
8
Explanation:
When Joe flips three coins simultaneously, the sample space represents all the possible outcomes or combinations of the coin flips. Each coin can have two possible outcomes: either heads (H) or tails (T).
For each coin, there are 2 possible outcomes (H or T). Therefore, the total number of outcomes in the sample space is:
2 * 2 * 2 = 8
So, there are 8 possible outcomes in the sample space when Joe flips three coins simultaneously.
