Power Set: the power set is asset of all
the subsets of its elements.
For example:
A = {1, 2, 3}
Then the
power set :Q = {ø,
{1}, {2}, {3}, {1,2}, {1,3}, {3,2}, {2,3}, {1,2,3}}
The number
of elements are always to 2n where n is number of elements in
original set. As in set A there are 3 elements. Therefore in power set Q there
are 23 = 8 elements.
