You can put this solution on YOUR website! It is almost impossible to display
the proper ordering of a truth
table on this site. May I suggest
you Google "truth table examples".
There you will see worked examples
that may help you.
Check the Wikipedia site on truth tables.
Cheers,
Stan H.

You can put this solution on YOUR website! Recall that the truth table for p -> q is
p.......q........p -> q
T.......T........T
T.......F........F
F.......T........T
F.......F........T
In other words, p -> q is only false when p is true and q is false. This is like saying that "if it rains, then it will be wet outside". If it does rain, but doesn't get wet, then the statement is false. In any other case, p -> q is true.
If we swap p and q to get q -> p, we then get
p.......q........q -> p
T.......T........T
T.......F........T
F.......T........F
F.......F........T
So the proper heading for the last column is q -> p
