To find the probability that a student chosen randomly from the class plays basketball or baseball, we add the number of students who play basketball to the number of students who play baseball, and then subtract the number of students who play both sports (to avoid double counting).
Number of students who play basketball or baseball = Number of students who play basketball + Number of students who play baseball - Number of students who play both sports
Number of students who play basketball or baseball = 5 + 6 - 2
Number of students who play basketball or baseball = 9
Therefore, there are 9 students who play either basketball or baseball. Since there are 20 students in total, the probability that a student chosen randomly from the class plays basketball or baseball is:
Probability = Number of students who play basketball or baseball / Total number of students
Probability = 9 / 20
Probability = 0.45 or 45%
In a certain Algebra 2 class of 20 students, 5 of them play basketball and 6 of them play baseball. There are 2 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?
