In a certain Algebra 2 class of 21 students, 12 of them play basketball and 14 of them
play baseball. There are 5 students who play neither sport. What is the probability
that a student chosen randomly from the class plays basketball or baseball?​

Answers

Answer:

Explanation:

We know there are 21 students in all, so that should be the denominator in this answer.

Then, to find the numerator, we need to find the number of students that play basketball and the number of students that play baseball, assuming that none of them play both sports. Just add those two numbers to get the numerator, and then put it on top of the 21.

You either typed this question incorrectly, or there is a mistake, because there are more kids that play basketball or baseball than there are students in the class.
