Question

Write down the all possible proper subset of the given set.
{1, 2}

✓

Answer

We know that if A is a set and B a subset of A, then B is called a proper subset of A. If $\text{B}\subseteq\text{A}$ and $\text{B}\not=\text{A},\phi$ and is written as $\text{B}\subset\text{A or B}\subseteq\text{A}.$
Hence, the proper subset are given by {1}, {2}.
