"Ask the Audience" is a lifeline used in the popular quiz show Who Wants to Be a Millionaire. Contestants can use this option when they are unsure of the answer to a question. They can poll the studio audience, who then provide their opinions on what they believe is the correct answer. The audience typically votes using keypads, and the results are displayed as a percentage for each answer choice. This lifeline can be particularly helpful, as it allows contestants to gain insight from a group of people, potentially increasing their chances of selecting the right answer and advancing in the game.
