Question 759137
Q:
Is there exactly 16 subsets and 24 subsets? If no, why?
-----------------------------------------------------------
A:
If a set has n elements, then the number of subsets is equal to {{{2^n}}}.
If a set has exactly 16 subsets, then {{{2^n}}} = 16 --> n = 4 (number of elements in a set). Therefore, a set can have exactly 16 subsets.
If a set has exactly 24 subsets, then {{{2^n}}} = 24 --> n = no solution in the set of non-negative integers. Therefore, a set cannot have exactly 24 subsets.
