Universal Set

1.       Suppose, while doing your all cleaning there was an ant on one of the pieces of paper kept near C.

2.       And now, because of you she is inside one of those small bags inside the big bag P.

3.       She comes out of her small bags and observes the things around her. Now whatever she observes, it is the only things that she is going to live with in rest of her life.

4.       That big bag P is now her entire Universe and for her, this bag P is the Universal Set.

5.       P is Universal Set for our poor ant because whatever she can find, it all belongs to the set P.

6.       Pity on the poor ant! Can’t you be more careful while doing your work! J

Power Set

1.       Enough of breaking and spreading pieces of paper. Time has come to now do cleaning!

2.       After breaking sets and tearing papers, how about putting them together now?

3.       So, by now you have got your paper pieces gathered near B, C, D, E, F, etc…

4.       Find small paper bags and put the pieces near each of the alphabets in separate bags.

5.       Put all these bags in a big bag and write P on the big bag. Also put an empty small bag inside the big bag.

6.       This P bag, my friends is your Power Set. Now you can happily go and dump this P bag and get rid of all your garbage from your table! J

Formalized representation:

Power set of A is P.

P = {ϕ,B,C,D,E,F…}
