The term "majority" refers to the greater part or more than half of a total group. In decision-making processes, such as voting, a majority is often required to determine the outcome. For example, if 100 people vote, at least 51 votes are needed for a decision to be considered the majority. In legal contexts, the concept of majority can also refer to the age at which a person is considered an adult, typically 18 years in many countries. This age signifies the point at which individuals gain full legal rights and responsibilities, such as the ability to vote or enter into contracts.
