In a certain Algebra 2 class of 20 students, 12 of them play basketball and 13 of them play baseball. There are 3 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?

85%

Step-by-step explanation:

1. Divide 100 by the maximum amount of students to get the percent value for every student (5% per student)

2. Subtract the number of students you know plays neither sport, leaving you with 17 students.

3. Multiply the remaining students by the percent percent value. 17 * 5 = 85%

(This takes into account that some students are playing both sports.)
