The Addition Principle states that if there are two or more mutually exclusive events, the total number of outcomes is the sum of the number of outcomes for each event. It is a fundamental concept in counting and probability.
Mutually Exclusive Events: Events that cannot happen at the same time. If one event occurs, the other cannot.
Probability: A measure of how likely an event is to occur, often calculated as a ratio of favorable outcomes to total possible outcomes.
Counting Principle: A fundamental rule in combinatorics used to count the number of ways multiple tasks can be performed.
