Quizplus · Accepted Answer

The sample space for flipping two coins simultaneously includes all possible outcomes, which are HH (heads and heads), HT (heads and tails), TH (tails and heads), and TT (tails and tails). Therefore, the correct answer is C, which lists all possible outcomes of flipping two coins. A only includes one possible outcome (either heads or tails), B includes only combinations of two possible outcomes, and D includes duplicate outcomes.
