Probability of Enjoying Rides

In an amusement park, there are 400 visitors. Among them, 250 enjoy roller coasters, 150 enjoy water rides, and 100 enjoy both. If a visitor is selected at random, what is the probability that the visitor enjoys at least one type of ride?

Let:

• A represent the set of visitors who enjoy roller coasters.
• B represent the set of visitors who enjoy water rides.

The required probability can be calculated using the principle of inclusion-exclusion.
