Step 1

A)

A is the set of students in the discrete math class.

B is the set of students at Arizona majoring in computer science.

B\A represents the elements in B but not in A.

Here B\A are the students at Arizona majoring in computer science but not in the discrete math class.

B\A : The set of all students at Arizona majoring in computer science and not taken the discrete math class.

Step 2

b)

A is the set of students in the discrete math class.

B is the set of students at Arizona majoring in computer science.

The students majoring in computer science in the discrete math class are the students who major in computer science and taken discrete math class.

That the set that represents the given details is \(\displaystyle{A}\cap{B}\).
