Question

calculate number of subset of null set ​

Answer 1

Step-by-step explanation:

It has only one subset, and that is the null set itself. Since the number of elements of the null set is 0, the number of its subsets has to be 2^0=1.

Answer 2

Answer:

Only one subset is there for a Null Set, i.e. the null set itself.

Step-by-step explanation:

• Subset : Set A is termed as a subset of Set B if all the elements of Set A are  present in Set B , that is, set A is contained inside Set B.

• Example: If set A has {a,b} and set B has {a,b,c}, then A is the subset of B because elements of A (a and b)are  present in set B.
• Null set or empty set  is the set that does not contain anything.

• The Null set is a subset of every set .
• The Null is also a subset of a Null set.
