If each X Y and Z is a set then F X Y Z is a set each elem

If each X, Y, and Z is a set, then F = { X, Y, Z} is a set, each element of which is a set. We say is a collection, each element of which is a set. Of course, the number of sets in such a collection is not restricted to 3 as in this simple case.

If each of X and Y is a set the \"X and Y are disjoint means that there is no element which belongs to both X and Y\"

Solution

SOL) X and Y are disjoint means that there is no element common to both . it is by definition of disjoint sets.so intersection is empty. example

if X={1,2,3} and Y={4,5,6} then they are called disjoint because they have no element in common.this is all by definition
