Fifty students were surveyed about their participation in hockey and baseball The results of the survey are 33 students played baseball

8 students didn't play hockey or baseball.

How many students played both hockey and baseball?

Solution:

Hi,the problem is not complete, the number of students playing hockey was not given.

We assume N students played hockey.

According to the Venn Diagram, we assume the number of students playing both hockey and baseball is x, so the equation is

(33 + N - x) + 8 = 50

x = N-9

If the number of students playing hockey is given, we can find the value of x.

For example, if N = 14, x = 5.
