Here is an example of how to build a truth table for a statement with three propositional variables

Thank you! Thank you! Struggling in a 6 week course remote. After looking at others on You tube, you brought it home !

When you create the columns of p, q, r can you start with any alternative or does it have to start with 4 trues and then the 4 falses

Thanks for the comment. I'm not really sure what you mean. The truth table is a way for analyzing statements, not arugments. An arugment is valid if the truth of its premises imply the truth of its conclusion. Here we are just analyzing a single statement.

If you were asking whether the satement was a tautology or a contradiction, it is neither, as evidenced by the fact that the last column has both T's and F's in it.

I was just confused on how false implies false is true?
