Question

State, which of the following pairs of sets are disjoint :

v:- {people living in Calcutta} and

{people living in west Bengal}

Answer 1

Step : Check whether the pair of sets are disjoint

Given:

{people living in Calcutta} &

{people living in west Bengal}

People of Calcutta are the people of west Bengal as Calcutta is a city of west Bengal.

And we know that Sets having no element in common are called disjoint sets.

Hence, the given pair of sets are not disjoint sets.
