So for this problem, we're going to make a list of the subsets of the set with elements, a, b, and c.
00:08
So you could have subsets with zero elements, with one element, with two elements, or with three elements.
00:21
So with zero elements, we just have the empty set.
00:25
So there's one choice there.
00:27
With one element, we could have a or b or c.
00:34
So there's three different sets, three different subsets that have one element.
00:39
With two elements, we could have a and b, a and c, or a and c.
00:53
So there are three subsets there...
