Write the set of elements in π and not in π.

First, why donβt we write all the numbers found in set π. Two, three, and six are found in π. One, seven, and nine are also part of π because itβs found inside the red circle. So we say that one, seven, nine is also part of set π. Set π is a subset of π. Itβs found inside set π. And it contains only one, seven, and nine.

We want to know the set of elements that are in π but not in π. And that would be the numbers two, three, and six. The set of elements located in π but not in π is the set two, three, six.
