p → q means “if p is true, q is true as well.” Recall: The only way for p → q to be false is if we know that p is true but q is false. Rationale: If p is false, p → q doesn't guarantee anything. It's true, but it's not meaningful. If p is true and q is true, then the statement “if p is true, then q is also true” is itself true.Oct 16, 2018 · Precalculus Mathematics Homework Help.
