Answer:

Step-by-step explanation:A family of sets is said to be union-closed if the union of any two sets from the family remains in the family. The conjecture states: For every finite union-closed family of finite sets, other than the family containing only the empty set, there exists an element that belongs to at least half of the sets in the family.
