If p∨q is true, then the negation is false.

That is, the proposition that both p and q are false is false.

Find the solution set when P and Q are true propositions, then find the complement set, and find the solution set when pq is false propositions. Then find the intersection and get the solution set of the proposition that both p and q are false. Then take the complement set.

Is the solution set of p ∞ Q.

All hands up, please adopt.
