Finding Power Set Examples | Set Theory, Subsets and Power Sets

How do we find the power set of a set? That's what we'll go over in today's set theory video lesson with 4 examples!

Remember the power set of a set S is the set P(S) consisting of all subsets of S. Don't forget to include the empty set and the set S itself! Also recall that the cardinality of the power set of S is equal to 2 to the power of the cardinality of S.

The outro music is by a favorite musician of mine named Vallow, who, upon my request, kindly gave me permission to use his music in my outros. I usually put my own music in the outros, but I love Vallow's music, and wanted to share it with those of you watching. Please check out all of his wonderful work.
