Intersection of Two Sets

The question:

when is the intersection of two sets equal to the null set?


The answer:

The set formed by the intersection of two sets contains those elements which appear in both sets.


For example:


Set A = {rock, horseshoe, glasses, lamp, book}

Set B = {computer, dishes, speaker, lamp, book}

. . . Both Set "A" and Set "B" contain the following elements: lamp, book

The intersection of Set “A” and Set “B” is the set which contains two elements: lamp and book.

A ∩ B = {lamp, book}



When sets have no elements in common, they are called disjoint sets. The intersection of disjoint sets produces a null set.

For example:

Set C = {rock, horseshoe, glasses, lamp, book}

Set D = {computer, dishes, speaker, whale, ship}




. . . The Intersection of Set "C" and Set "D" produces an EMPTY SET (a NULL Set). Set "C" and Set "D" have no elements in common with one another.

C ∩ D = {}

C ∩ D = Ø


Thanks for writing.
