Is this answer to a question counted as a legitimate answer

Question

I was doing an assignment and this is one of the questions

---

Q4) (a) Find a compound proposition using only p, q, ¬, and the connective OR with the truth table at the right  (4 marks) 

p	q	?
T	T	F
T	F	F
F	T	T
F	F	F

 

(b) Find another compound proposition that is based on the previous truth table (4 marks)

---

So my answer to part (a) is:  NOT (p OR NOT q)

And my answer to part (b) is: NOT (NOT (NOT (p OR NOT Q) 

I was wondering is my answer to part (b) is counted as a legit answer to the question, because it's right but it's not really expanding the information given and just using the previous answer.

Answer 1

This is the assignment question, so we cannot verify if the answer is correct or not, however it seems correct for part a ;-)

For part b, adding two not that does not have any effect could be considered as a right answer, but can you find any other compound proposition as well?

Comments

Well I did have another solution which is the following,

NOT(p OR NOT q) OR  NOT(p OR NOT q)

I feel like this would be a better answer, but I still have the same concern as of the first one
