Question
Let P be the power set of the set {a,b,c,d}, what is n(P)?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The power set of a set with n elements has 2^n elements. Here, the set has 4 elements ({a,b,c,d}), so n(P) = 2^4 = 16.
Hint
If a set has n elements, its power set has 2^n elements.
