I am trying to construct a truth table for the statements 'P' and 'Q' - I am not told what these statements are so I guess they're random, anything ones, and I now need to construct a truth table for the statement:

(not P) or (not Q):

I did:

P...Q.....(not P)...(not Q).....(not P) or (not Q)

T...T........F...........F....................T

T...F........F...........T...................

F...T........T...........F..................

F...F........T...........T

That was my attempt at drawing a table, the very top line is the heading bit of the table, the rest are its "entries", which hopefully are in the right spaces, if you want me to clear it up, please ask

I am not sure what to put into the final (not P) or (not Q) column. Does this column mean that you want either (not P) to be true OR (not Q) to be true, as P and Q are both true, from the first 2 columns?

I am not too sure what I am looking for to put into the final column?

If you want to know the exact question, it is from Peter J. Eccles's "An introduction to mathematical reasoning", in chapter one, exercises 1.2.

Thank you
