Explanation:
Valid is something effective, legally binding or able to withstand objection.
In deductive reasoning, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. It is not required for a valid argument to have premises that are actually true, but to have premises that, if they were true, would guarantee the truth of the argument's conclusion.

An argument is a set of statements expressing the premises and an evidence-based conclusion.
