We want to write these as p and qs.
00:03
So, um, p is going to be 1 plus 2 equals 3.
00:13
Q is going to be 3 is, um, we'll say 3 is odd.
00:23
So the first one is if 1 plus 2 is not equal to 3, so if not p, then q, then 3 is odd.
00:34
Um, and then we see.
00:38
That if 1 plus 2 is not 3, we'll have to false statement, so this statement must be true.
00:44
Because the first statement is false, so the whole statement is true.
00:47
If 1 plus 1 is equal to 2, so that could be a different p statement, so this could also be, or 1 plus 1 is equal to 2.
00:57
We have if p or if and only if, so p if and only if, q...
