If a set has n elements , it has 2n subsets.
Example : The set {1,2,3,4,5,6} has 26 = 64 subsets.
Note that the null set and the set itself are included in this total.

The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.
No. The number of subsets of that set is strictly greater than the cardinality of that set, by Cantor's theorem. Moreover, it's consistent with ZFC that there are two sets which have different cardinality, yet have the same number of subsets.
The subsets of a fraction refer to the individual components that make up the fraction. For example, the subsets of the fraction 3/4 would be the numerator (3) and the denominator (4). In set theory, a subset is a set that contains elements of another set, so in the context of fractions, the subsets are the parts that form the fraction.
Cardinality is simply the number of elements of a given set. You can use the cardinality of a set to determine which elements will go into the subset. Every element in the subset must come from the cardinality of the original set. For example, a set may contain {a,b,c,d} which makes the cardinality 4. You can choose any of those elements to form a subset. Examples of subsets may be {a,c} {a, b, c} etc.
Hi Suppose, I found that number of subsets of set S having n elements can be found by using formula 2^n, where n is number of elements of S. Let S(n) represents number of subsets of set S having n elements. S(n) = 2^n S(n+1) = 2^(n+1)
