In a class of 40 students, 19 play tennis, 20 play netball and 8 play both of these sports. A student is randomly chosen from the class. Determine the probability that the student play tennis. Use the empty Venn diagram to help you arrive at your answer. Write your answers as a percent to one decimal.

67.5%

Step-by-step explanation:

Using the venn diagram, you put 19 students in one circle that play tennis

For the other circle you put 20 students play netball

And in the middle, you put 8 students play both.

To find the probability, add 19 students that play tennis and the 8 students that play both

19+8=27

27/40 would be your probability of students that play tennis.

100 divided by 40 equals 2.5

2.5 times 27 equals 67.5
