Question

if A sub set of B , B is known as super set then A is known as​

Answer 1

$\huge\mathfrak{Sets}$

✴If A and B be any two sets , then A is called a subset of B if every member of A is also a member of B.

✴If A is contained in B, we may also say that B contains A or B is a superset of A .

✴If there exists one element in a A which is not a member of B , then A is not a subset of B .

$\huge\mathfrak{Example}$

If A = {2,3,5} and B = {1,2,3,4,5,6} , then every member of A is a member of B , so A is a subset if B.

Remarks

✍Every set is a subset of itself.

✍Since the empty set has no elements, empty set is a subset of itself.

✍Every set is a subset of universal set.
