Answer:

13 / 30

Step-by-step explanation:

The probability an be represented by the number of desirable outcomes over the total outcomes. We know the total is 30 since there are 30 students to be chose from. Now, we need to find the number of students who play basketball and baseball. We can add the two values we are given:

7 + 11 = 18 students

BUT.... we are over-counting the students who play both. We need to subtract those 5 students, since the are counted twice, and that way, they will only be counted once:

18 - 5 = 13 students

Using the formula for probability at the top, we get:

13 / 30
