There is an area of free (but illegal) parking near an inner-city sports arena. The probability that a car parked in this area will be ticketed by police is 35, that the car will be vandalized is $.15$, and that it will be ticketed and vandalized is 10 . Find the probability that a car parked in this area will be ticketed or vandalized

Key Concepts

Probability

Probability is a quantitative measure that expresses the likelihood of a particular event occurring as a number between 0 and 1, or as a percentage. It forms the foundation of probabilistic reasoning and is used to model and analyze random events.

Union of Events

The union of two events A and B represents the scenario where at least one of the events occurs. Its probability is calculated by taking the sum of the probabilities of each event and then adjusting for any overlap to avoid double counting.

Intersection of Events

The intersection of two events A and B is a measure of the probability that both events occur simultaneously. This concept is crucial when events are not mutually exclusive, meaning they can happen at the same time.

Inclusion-Exclusion Principle

The inclusion-exclusion principle is a fundamental rule in probability theory used to compute the probability of the union of multiple events. It corrects for the overcounting of outcomes appearing in the intersections of events by subtracting the probabilities of the intersections.
