In this problem, we've been given set a and set b and told that they have been chosen as subsets of the universal set a.
00:09
We've been asked to find a complement intersect b complement.
00:14
So we have to remember is that the complement is everything in the outside set that was not included in the subset.
00:21
So if we want to write down what a complement is, we're going to go through and pick out things from the universal set that are not in a.
00:28
So since one is in a, it's not going to be in its complement.
00:34
So the first not thing that we get in the universal set here is going to be four, and then five can't be included, six can be included.
00:43
Seven and eight are in a, but nine and ten are not.
00:47
So four, six, nine, and ten are going to be the complement for a.
00:51
Now let's take a look at b.
00:55
B has a one, a two...
