Question

write down all the subsets of the set {1,2}​

Answer 1

Answer:

Step-by-step explanation:

As we know empty set is subset of all set,

So it's subsets are

{1},{2},{1,2},{}

Answer 2

The subsets of {1,2} are { }, {1}, {2}, {1,2}.

Given:

The given set is {1,2}.

To Find:

we need to find the subsets of the given set.

Solution:

Consider two sets A and B

A is said to be a subset of B if all the elements of A are present in set B.

The number of subsets for a given set of 'n' elements is

${2}^{n}$

A null set is a subset of every set.

A null set is also called an empty set which tells it is a set containing no elements. It is depicted as { }.

This set contains 2 elements. That implies it has 4 subsets.

Therefore, the subsets are { }, {1}, {2}, {1,2}.
