In order to solve the problem, you need to clearly write and understand the condition.
You are given the set consisting of 5 elements {a, b, c, d, e}.
You are asked to list all its subsets.
Let me start
{a}, {b}, {c}, {d}, {e},
{a, b}, {a, c}, {a, d}, {a, e},
{a, b, c}, {a, b, d}, . . . .
Can you continue and complete it?
In all, the original set has 
= 32 subsets including the empty set {} and the set itself as a subset {a, b, c, d e}.
