Okay, so the expression that we are given here is a bar union b, and then that's going to be intersected with, so that's going to be intersection c bar minus a.
00:17
So what does this mean? well, a bar is everything that is outside of a, and then c bar minus a.
00:24
That is everything that is outside of c but also not in a.
00:30
And then a bar union b is everything in b or, right? the union in b or, so everything in b or that's outside of a.
00:40
And the intersection is the common area, right? so that's going to be the common area between everything that is in b or outside of a and everything outside of c, but also not in a.
00:57
So if we go ahead and we make a picture of this, we have two sets, a, b, and c...
