Truth Tables (part 3)

This short video is an introduction to using truth tables to determine the validity of symbolized natural lanuage arguments in deduction.

I'm a bit confused sir. Since in Unit 1(Evaluation of Arguments 13:00) you said that we only know an argument with false premises and a true conclusion is invalid, others' Validities are question marks. How can we know here at this video at 7:50 that without denying the antecedent then the argument must be valid?


p.s. Thanks for the great videos you have made, they help me a lot. :)
