Logic: Possible Typo in Textbook

Dembadon

It's possible that I'm not understanding the diagram and their reasoning, but I wanted to check with some people here before I come to a conclusion.

1. The problem statement, all variables and given/known data



2. Relevant equations



3. The attempt at a solution

I don't understand why the book says the formula is false, yet there is a "T" at the bottom of the computation.

The book is, Understanding Symbolic Logic, 5th ed. by Virginia Klenk.

The 'T' at the bottom of the diagram is a typo. It should be an 'F'. The words you highlighted are correct.

Thank you for verifying, Stephen.
