At a sports event, a fair coin is flipped to determine which team has possession of the ball to start. The coin has two sides, heads, $(H)$, and tails, $(T)$. Identify the correct experiment, trial, and outcome below: Select all that apply: The experiment is identifying whether a heads or tails is flipped. The experiment is flipping the coin. A trial is flipping a heads. A trial is one flip of the coin. An outcome is flipping a tails. An outcome is flipping a coin once.

Step 1 ：The question is asking to identify the correct definitions of experiment, trial, and outcome in the context of a coin flip at a sports event.

Step 2 ：An experiment in probability refers to the process by which an observation or measurement is obtained. In this case, the experiment would be flipping the coin.

Step 3 ：A trial refers to each individual instance or repetition of an experiment. In this case, a trial would be one flip of the coin.

Step 4 ：An outcome refers to the result of a single trial. In this case, an outcome would be getting a heads or a tails.

Step 5 ：So, based on these definitions, the correct statements would be: The experiment is flipping the coin. A trial is one flip of the coin. An outcome is flipping a heads or a tails.

Step 6 ：\(\boxed{\text{The correct statements are: The experiment is flipping the coin. A trial is one flip of the coin. An outcome is flipping a heads or a tails.}}\)
