Find π΄ intersection πΆ using the Venn diagram.

First, we need to know this little upside-down β. This symbol β the intersection symbol β tells us that weβre looking for values found in both π΄ and πΆ. The space here between π΄ and π΅ with the numbers 11 and six is the intersection of π΄ and π΅. The numbers 11 and six are found in set π΄ and in set π΅. The numbers 10 and eight are the intersection of π΅ and πΆ. 10 and eight are found both in set π΅ and in set πΆ. And weβre trying to determine are there any values that are found in set π΄ and in set πΆ.

Letβs list out the values of set π΄. Set π΄ is four, five, six, nine, 11. We can do the same thing for set πΆ β set πΆ: zero, two, seven, eight, and 10. Now, is there any number thatβs found in both π΄ and πΆ? π΄ and πΆ donβt share any values. When two sets do not share any values, their intersection is called the empty set. We also might call this the null set.

The intersection of set π΄ and set πΆ is the empty set.
