Question

ia A={p, q, r}, B={q, r, m, n} then write the elements of AnB​

Answer 1

Step-by-step explanation:

ia A={p, q, r}, B={q, r, m, n} then write the elements of AnB

Answer 2

Given :-

Two sets i.e A = { p , q , r } and B = { q , r , m , n }

To Find :-

A ∩ B = ?

Used Concepts :-

• A ∩ B is the set consisting all the common elements of A and B sets respectively .

Solution :-

Here , A = { p , q , r }

B = { q , r , m , n }

Therefore , A ∩ B = { q , r }

Hence , The required answer is { q , r } .

Additional Information :-

For a Set "A" :-

• The power set is the set of all the subsets of "A"
• If n( A ) = m , then no. of subsets of "A" is 2^m.
• Let , us consider another set B , Then A is called the proper subset of B only if All elements of A belongs To B , but there is at least one element in B , that not belongs to A .
• If n( A ) = m , then number of proper subsets of A = 2^m - 1 .
• The empty set is the subset of every set ( Including itself ) .
• Every set is a subset of itself but not proper subset.
• The empty set is a proper subset of every set ( Except Itself ) .
