• 7 is greater than 4 and 6 is less than 7

• None of the above

Answer 1

7 is not greater than 4 and 6 is not less than 7

Explanation:

Let p : 7 is greater than 4

and q : 6 is less than 7.

Then, the given statement is disjunction p v q.

Here, ∼ p : 7 is not greater than 4.

and ∼ q : 6 is not less than 7.

∴ ∼ (p v q) : 7 is not greater than 4 and 6 is not less than 7.
