Answer:
1 member took literature but not mathematics.
Step-by-step explanation:
We can draw a Venn diagram for the given question.
In a fraternity total number of members = 32
Number of members who took mathematics M = 18
Number of members who took both mathematics and literature (M∩L) = 5
And number of members who took neither mathematics nor literature = 8
Therefore, number of members who took literature but not mathematics
= 32 - [(18 + 5) + 8]
= 32 - [23 + 8]
= 32 - 31
= 1
Therefore, 1 member took literature but not mathematics.
