Need some help with discrete math. I'm lost as fuck atm.

>verify {p∨q, ~p} ⊨ q
>verify {p→r, q→r, p∨q} ⊨ r

So I truth table each one of those hypotheses and look for wherever both hypothesis and conclusion is T, right?

Do you know your rules of propositional logic?
The first one is a disjunctive syllogism and the second is a constructive dilemma.

Lucky me then.

It says to simply verify, so I assumed just doing truth tables or using rules and laws.
