 I'm going to talk about how to fill in a basic truth table. If you can get the rhythm down or the pattern down, it makes it much easier to when you're starting a truth table to fill in the P and Q statements correctly so you don't have to worry about that. To guarantee that you have every combination possible, P will, you'll always set it up to be P is true and true or the first statement whether it's P or some other letter. It's true, true, and then false, false. Then for the second statement, you'll always set it up true, then false, alternating, true and false. That's how you set up a basic truth table.
