Question

A set contains 2n + 1 elements. The number of subsets of
this set containing more than n elements is equal to
(a) 2^n-1
(b) 2^n
(d) 2^2n
(c) 2^n + 1​

Answer 1

Answer:

(c) 2^n+1

Step-by-step explanation:

As the set contains 2n+1 elements according to your question,

We know a general formula for calculating its number of subsets that is, 2^n for n elements

So the total number of subsets for the given set will be equal to, 2^n+1

So therefore option (c) 2^n+1 is correct
