Question

if A={3, 4, 5} and B= {6, 7, 8},
then show that A and B are disjoint sets.​

Answer 1

Step-by-step explanation:

Given sets are :-

A={3, 4, 5} and B= {6, 7, 8}

It is clear that there is no element in common in both the sets A and B .

Therefore,A and B are disjoint sets.

(or)

A={3, 4, 5} and B= {6, 7, 8}

AnB={3, 4, 5} n {6, 7, 8}={ }

Since A inter section B=AnB={ }

A and B are dis joint sets

Dis joint sets:-

Let A and B are two non empty sets then there is element in common in both A and B i.e.

AnB={ } empty set then A and B are called disjoint sets.
