Question 1

What is the cardinality relationship established by Cantor's theorem?

  • The cardinality of set A is greater than the power set P(A)
  • The cardinality of set A is less than the power set P(A)
  • The cardinality of set A is equal to the power set P(A)

💡 Hint: Remember the definition of the power set.

Question 2

True or False: The power set of a finite set always contains 2^n elements, where n is the number of elements in that set.

  • True
  • False

💡 Hint: Think about the counting of subsets.
