Question

If A = {set of whole numbers less than 6} and B = {set of prime numbers less than 7}, then

• A. B is a subset of A
• B. A is a subset of B
• C. B is a singleton set
• D. A and B are disjoint sets

Answer 1

The correct option is A

B is a subset of A

A = {set of whole numbers less than 6}

A = {0,1, 2, 3, 4, 5}

B = {set of prime numbers less than 7}

B = {2, 3, 5}

All the elements of set B are also elements of set A.

So, A is a superset of B.
