Okay, so in this question we have this statement p and p or q.
00:11
And basically we want to know how can we simplify this logical equation.
00:19
Well, i'm going to draw a little chart with p here, q here, and i'm going to write p and p and p or q here.
00:37
And in this chart, we're going to write all the possible values of p.
00:43
So p can be true.
00:48
I will write it twice.
00:49
You will know why true, or it can be false.
00:55
Same thing for q.
00:56
Q can be true, false, true.
01:03
So these are all the combinations that p and q can take.
01:08
They can both be true, one of them can be false, or they can both be false.
01:13
And now we're going to compare what we see in those columns to what we see in the final column.
01:23
So if both of these statements are true, if p and q are true, then p, then we will have true and true or true, which is, of course, true.
01:42
Let's suppose that p is false, that p is true, but that q is false.
01:54
So true or false here will be true.
01:58
So you have true and true, which is equal to true.
02:05
Let's suppose that p is false and that q is true...
