Final answer:
The statement is true because one of the payoffs matches one of the possible outcomes of flipping two coins.
Step-by-step explanation:
The question asks whether the statement is true or false. The statement says that in a game where a coin is flipped twice, the payoffs for the possible outcomes are as follows: H-H: Win 20, H-T: Win 9. To answer the question, we need to determine if these payoffs can be assigned to the outcomes of flipping two coins. Since there are only two outcomes for flipping two coins (HH and HT), and one of them matches with the given payoff, the statement is True.
