Find the Power Set A=(a,b,c)

The power set of a set ${\displaystyle S}$ is the set of all subsets of ${\displaystyle S}$. The first subset will be set ${\displaystyle S}$ itself. Next, find all subsets that contain one less element (in this case ${\displaystyle 2}$ elements). Continue with this process until finding all subsets including the empty set.

Power Set = ${\displaystyle \{\{a,b,c\},\{a,b\},\{a,c\},\{b,c\},\left\{a\right\},\left\{b\right\},\left\{c\right\},\left\{\right\}\}}$
