Question

In a certain Algebra 2 class of 22 students, 13 of them play basketball and 10 of them play baseball. There are 8 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?​

Answer 1

13 - 8 = 5 students play basketball only

10 - 8 = 2 students play baseball only

P(basketball or baseball) = (2 + 5 + 8)/22

= 15/22
