They are collections of some, or all, of the elements of the set. A set with n elements will have 2^n subsets.
That means, figure out how many different subsets a set has. In general, if a set has n elements, it has 2n different subsets.
If you have a set of 6 elements, you can make a total of 26 different subsets - including the empty set and the set itself.
If the set has "n" elements, then you can make 2n different subsets. The number of subsets will always be greater than the size of the set, both for finite and for infinite sets.
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.
Relative subsets refer to subsets that are defined concerning a larger set or context. For example, if you have a universal set ( U ) and a subset ( A ) of ( U ), then relative subsets can be other subsets formed from ( A ) or the elements of ( A ) in relation to ( U ). This concept is often used in set theory and probability to analyze relationships between different groups within a larger framework.
8 subsets
An element doesn't have subsets. Sets can have subsets.
Two. The set {x} has the subsets {} and {x}.
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.
A finite set with N distinct elements has 2N subsets.
Elements belong to subsets: subsets contain elements (from the parent set).
If the set has n elements, the number of subsets (the power set) has 2n members.
