In this problem we are required to complete the truth tables for the statement, not of g or h or not g and not h.
00:09
For the first table, we are going to use another table and introducing a table which will include a column for g or h.
00:23
So the input values are g and h which are true and true so g or h would be equal to if g is true h is false then g or h is true.
00:35
If g is false h is true then g or h is true and if g is false h is false then g or h is false.
00:44
Now not of g or h will be the opposite.
00:49
So we have false for all the truths and true for all the false.
00:54
Now this is the required table for this problem.
01:00
Next we have a another table and we have introduced to another columns which is not of g and not of h.
01:07
Now g is true so not of g would be false and when g is false then not of g would be true at both places.
01:17
If h is true then not of h would be false and if h is false then not of h would be true.
01:26
So we have false and true over here.
01:30
For true over here we have false and for h is equal to false.
01:34
Knot of h is true.
01:38
Now we can find not of g and not of h...
