In probability theory, a trial refers to a single occurrence of an experiment or observation, such as flipping a coin. An event is any outcome or set of outcomes of a trial, such as getting heads or tails when flipping a coin. Therefore, the act of flipping a coin is a trial, and each unique outcome (heads or tails) is an event. Option B correctly identifies the flipping of a coin as a trial and the possible outcomes as events.
