Question

In a certain Algebra 2 class of 30 students, 18 of them play basketball and 16 of them play baseball. There are 8 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?

Answer 1

Number who play at least one sport = total − neither = 30 − 8 = 22.
Probability = 22/30 = 11/15 ≈ 73.33%.
