Hello students, let's discuss the question.
00:04
Here we have to determine whether the statement is a totology, self -contradiction or neither.
00:10
So the statement is negation q implies b, this whole or q.
00:18
So the totology is basically the statement which is always true and self -contradiction is the statement which is always false.
00:36
So we have to generalize this.
00:39
So for this we will make the truth table.
00:42
So p q let p have values true, true, false, false.
00:52
This is having true false, true false.
01:01
Now the negation.
01:04
Q is the opposite.
01:07
So true becomes false, false become true, true becomes true, true becomes.
01:11
False and false become true.
01:15
So negation q implies p become we will see this and this.
01:24
So we'll get true, true, false, false.
01:32
Now in the last we'll find negation q implies p, 4 or q...
