Question 485403: Can someone help me make a truth table for ~q → (~p V q)?
Answer by chessace(471)   (Show Source):
You can put this solution on YOUR website! I'm going to do a videao on this one eventually, but here it is.
Unfortunately spaces get ruined by fonts, so I'll transpose rows and columns.
There are 4 rows (now columns) so each line below is an expression followed by 4 values, then a comment, a total of 6 things separated by spaces, not well lined up:
p T T F F (1. independent var)
q T F T F (2. independent var)
~p F F T T (3. from 1)
~q F T F T (4. from 2)
~pVq: T F T T (5. from 3 and 2)
entire: T F T T (from 4 and 5)
This is the step by step version, a pure table would remove lines 3 thru 5.
