Answer:

26 female students

Step-by-step explanation:

Let U be the set of all protesters, such that n(U) = 76

Number of male protesters n(M) = 32

If 22 of the males are students, males that are non-student will be (32-22) = 10

The number of female protesters is n(F)

Represent using the Venn diagram

where y is the total number of female students

Get the total number of females

Number of female protesters = 76 - number of male protesters

Number of female protesters = 76 - 32

Number of female protesters = 44

Female protesters = female students + non-female students

44 = female students + 18

44 = y + 18

y = 44 - 18

y = 26

This shows that 26 female students are protesting
