Okay, here's my bend diagram, three circles, a, b, and c overlapping.
00:05
And i want to work out, well, this symbol here means intersect or overlap.
00:10
So where do those three sets, a complement, b complement, and c complement overlap? well, one approach here, draw or shade each one separately.
00:22
So in blue i'm going to shade a complement.
00:25
That just means anywhere outside of circle a.
00:30
Ignore circle b and c completely.
00:33
Just shade in one given color, the area outside of circle a.
00:39
Then we'll do b next, going in green.
00:43
So b complement is anywhere outside of circle b.
00:48
Again, ignore totally a and c.
00:52
Just shade anywhere not in circle b.
00:57
The last one here, we have c complement...
