"Not Both" is a logical concept that refers to a situation where two conditions cannot be true at the same time. It implies that if one condition is true, the other must be false. This principle is often used in decision-making and problem-solving to clarify options and outcomes. In everyday scenarios, "Not Both" can apply to choices like choosing between two job offers or selecting a meal option. For instance, if you choose to eat pizza, you cannot also choose sushi for that same meal. Understanding this concept helps in making clear and effective decisions.
