A survey conducted among 120 students at a high school revealed the following about their preferences for extracurricular activities:
- 45 students participate in sports.
- 30 students participate in the arts (music, theater, etc.).
- 25 students participate in both sports and arts.
What is the probability that a randomly chosen student participates in either sports or arts?
Note: Use the principle of inclusion-exclusion to calculate the number of students participating in at least one of the activities.
