Subset :-

A set contained within another set is known as subset. eg:

A={1,2,3,4,5}  and B={1,2} then B is said to be the subset of A.

Power set :-

Collection of all subsets of a set is defined as power set of that set.

Let A be a non-empty set.

Then the power set of A is the set of all sub sets of set A.It is denoted by P(A)
