## Homework Statement

Here are three problems from an exam and I'm not sure i understand the wording... almost like we're supposed to get these wrong.

4. The Boolean expression of the OR between minterm 6 and minterm 7 using variables ABC (A being the MSB and C being the LSB) is

{(A)} AB

(B) AC

(C) BC

(D) A+B

(E) A+C

6. The Boolean expression of the AND between minterm 6 and minterm 7 using variables ABC (A being the MSB and C being the LSB) is

{(A)} 0

(B) 1

(C) A

(D) A'

(E) B

15. The Boolean expression of the OR between maxterm 6 and maxterm 7 using variables ABC (A being the MSB and C being the LSB) is

(A) 0

{(B)} 1

(C) A

(D) A'

(E) B

Correct answers are marked.

## The Attempt at a Solution

I did a k map and got AB as the sop for minterm 6 and minterm 7, and (A' + B') for the pos between maxterm 6 and 7, and AB looks like the answer for 4.

My problem is i have no idea what the questions are asking for,...well that and the TA didn't respond to my email :tongue:
