In this problem, we're asked to find all the subsets of set a.
00:07
And this is a tricky one because there are a lot of different subsets, so we're going to need to be very organized in how we do this.
00:13
So first of all, we want to start with the empty set, the set that has no elements.
00:18
That's considered a subset.
00:20
We can also check off our list the set that has all the elements, one, three, five, and seven.
00:25
So we got the easy ones done.
00:27
We also have the sets that contain only one element, so that would be the set with one, the set with three, the set with five, and the set with seven.
00:39
Okay.
00:40
Now it's going to get a little trickier because we have variations on the sets that have two elements.
00:46
We could have one in three.
00:49
We could have one and five.
00:51
We could have one and seven.
00:54
We could have three and five...
