A set with N elements has 2N subsets.
512 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.
A set with 50 elements has 250 subsets.
If the set has n elements then it has 2n subsets.
8 subsets
A set with 9 elements has 2^9 = 512 subsets.
An element doesn't have subsets. Sets can have subsets.
A set with N elements has 2N subsets.
512 subsets
If the universal set contains N elements then it has 2N subsets.
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.
Elements belong to subsets: subsets contain elements (from the parent set).
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.
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 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.
A set with 50 elements has 250 subsets.
