How many subset are there in given set?

If the set has n elements then it has 2n subsets.


How can you get the number of subsets?

Let's say the set S has n elements. An element can be either in the subset or not in the subset. So There are two ways for one element. Therefore the number of subsets of a set of n elements is 2 multiplied n times which is 2^n


How do you count the subset of a certain set?

A finite set, consisting of N elements, will have 2N subsets.


WHAT IS THE Proof that set N has 2 POWER N subset?

Let S be a set which has N elements. Consider in how many ways we can choose a subset. List the N elements of the set S. Let the names of the N elements be, x1, x2, x3, . . . xN For an arbitrary subset, we have two choices for x1. Namely, x1 might or might not be in the subset. We have two choices for x2. Namely, x2 might or might not be in the subset. We have two choices for x3. Namely, x3 might or might not be in the subset. . . . We have two choices for xN. Namely, xN might or might not be in the subset. Now we can easily count the total number of ways to choose a subset. 2 choices for x1 times 2 choices for x2 times . . . = 2 to the Nth power choices of ways to choose a subset. This proves that the number of subsets of a set with N elements is 2 raised to the Nth power. Kermit Rose


What is the no of generator in n order group?

In abstract algebra, a generating set of a group is a subset of that group. In that subset, every element of the group can be expressed as the combination (under the group operation) of finitely many elements of the subset and their inverses.


How does cardinality relates to number of subset of a set?

If a set has "n" elements, then it will have 2n subsets. This number of subsets is always larger than the number of elements - whether the set is finite or infinite.


Why an empty set is a subset of every set?

An empty subset is a part of every set because it is necessary to satisfy the equation of subsets which is 2n. n= (number of elements). Therefore, an empty set is required to satisfy the formula of subsets.


What are the possible subset of set B?

It is not possible to answer the question without information about the set B.All that can be said is that if set B has n elements, that is, if the cardinality if B is n, then there are 2n possible subsets of B.


What is the relationship of number of elements to number of subset?

A finite set, with n elements has 2n subsets, including the empty set and itself. For infinite sets the number of subsets is the same order of infinity.


How many patterns of subset can you make from a set?

given any set of n objects, there are 2^n subsets. This comes from the fact that each item is either in or not in any given subset. So for all n objects, each one has two possibilities, either it is or is not in a subset. Then 2^n come from the multiplication principle.


How many subsets does a set N element have?

A set with N elements has 2N subsets.


Prove that A contains N elements and the different subsets of A is equal to 2?

Assuming the question is: Prove that a set A which contains n elements has 2n different subsets.Proof by induction on n:Base case (n = 0): If A contains no elements then the only subset of A is the empty set. So A has 1 = 20 different subsets.Induction step (n > 0): We assume the induction hypothesis for all n smaller than some arbitrary number k (k > 0) and show that if the claim holds for sets containing k - 1 elements, then the claim also holds for a set containing k elements.Given a set A which contains k elements, let A = A' u {.} (where u denotes set union, and {.} is some arbitrary subset of A containing a single element no in A'). Then A' has k - 1 elements and it follows by the induction hypothesis that (1) A' has 2k-1 different subsets (which also are subsets of A). (2) For each of these subsets we can create a new set which is a subset of A, but not of A', by adding . to it, that is we obtain an additional 2k-1 subsets of A. (*)So by assuming the induction hypothesis (for all n < k) we have shown that a set A containing kelements has 2k-1 + 2k-1 = 2k different subsets. QED.(*): We see that the sets are clearly subsets of A, but have we covered all subsets of A? Yes. Assume we haven't and there is some subset S of A not covered by this method: if S contains ., then S \ {.} is a subset of A' and has been included in step (2); otherwise if . is not in S, then S is a subset of A' and has been included in step (1). So assuming there is a subset of A which is not described by this process leads to a contradiction.
