It's been years since high school, but I have been asked to help tutor. Please help me, because when I reviewed the material, I got confused.

For Example:

"If I go to work, then I will get paid"

Hypothesis: "If I go to work" (P)

Condition: "I will get paid" (Q)

So, a truth table can be made: (And from here I interpret it as I think it should be)

P | Q | Result

T T T "I went to work, I got paid" Makes since, so its all true.

T F T "I went to work, I didn't get paid" Makes no since, so its all false.

F T T "I didn't go to work, I got paid"

F F T "I didn't go to work, I didn't get paid" Makes since, it's true.

The bolded statement I am confused on. Initially, I think it would all be false... But the high school provides an online tutor video, and they say, "If you cannot determine the truth, then it is true by default". I'm confused! Please help!
