$\{-1,0,1\}$ ગણના બધા જ ઉપગણોની યાદી બનાવો.

Option A
Option B
Option C
Option D

Solution

Let $A=\{-1,0,1\} .$ The subset of $A$ having no element is the empty set $\phi .$

The subsets of $A$ having one element are $\{-1\},\{0\},\{1\} .$

The subsets of $A$ having two elements are $\{-1,0\},\{-1,1\},\{0,1\} .$

The subset of $A$ having three elements of $A$ is $A$ itself.

So, all the subsets of $A$ are $\phi,\{-1\},\{0\},\{1\},\{-1,0\},\{-1,1\}$ $\{0,1\}$ and $\{-1,0,1\}.$
