Question

No of occurrences of an element of set in a power set

Answer 1

Explanation:

We take all elements of P(B), and by the inductive hypothesis, there are 2n of these. Then we add the element x to each of these subsets of B, resulting in another 2n subsets of B. This exhausts the list of subsets of B, and so the total is 2n + 2n = 2(2n) = 2n + 1 elements of the power set of A.
