Answer:
The students in a school who do not walk to school this morning
Explanation:
From the question, we understand that:
The universal set is the set of students in a school
Let set A represents the set of students who walked to school
So:
A = students who walked to school
Represent the complement of A with A'.
In sets, A' is the direct opposite of A.
Hence:
A' = set of students who do not walk to school
