Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Notice how the truth table for p ^ q has a last column of T, F, F, F
Flip everything to get F, F, F, T, which is exactly the last column in the given table above.
So we go from p ^ q to ~(p ^ q)
Now use De Morgan's Law to simplify...
~(p ^ q)
~p V ~q
So the full table is...
| p |
q |
~p V ~q |
| T |
T |
F |
| T |
F |
F |
| F |
T |
F |
| F |
F |
T |
