If a set A has 5 elements, what is the number of elements in its power set, n(P(A))?

  • A.5
  • B.10
  • C.25
  • D.32

Answer: D

The power set of a set A, denoted P(A), is the set of all subsets of A. If a set A has 'n' elements, its power set has \(2^n\) elements.

Here, n = 5.

Number of elements in P(A) = \(2^5 = 32\).
