Hi, I've attached the question to this thread. For a) i've already done the tree but not sure how to find the truth value.
Here is a copy of the question if the attached question doesn't work. http://img837.imageshack.us/i/parsetrees.png/

Hi Soroban,
For the first one, did you type the question out right by swapping some of the formulae around or is there a typo as it doesn't match my question. Also how do you know which is true and which is false? I mean the p q and r are obviously T, T and F as the question says but how do you know that the implies arrow is F? Also, what do the little numbers underneath each table represent? lol sorry for all the questions but this is my first time attempting these kind of questions.
Thanks kindly.
