That is called the UNION of the two sets.
If all elements of set A are also elements of set B, then set A is a subset of set B.
Well, honey, I hope you're ready for this math lesson. A set with 6 elements can have 2^6, which is 64 subsets. That's right, 64 ways to slice and dice those elements. So, grab a calculator and start counting, darling!
union means to group the given sets. where as intersection means to pick out the common elements from the given sets. if set a has 1,2,3 elements and B has 1,2,3,4,5. then its union will have 1,2,3,4,5 as its elements. and its intersection will have 1,2,3 as its elements.
There is, because {0} has one element, 0. The set {0} therefore can have infinite sets, providing that, all sets are either null or has one element, 0.
It is 2^100 because each of 100 elements can either be in or out. By the way the answer is 2^100-101, because there is one subset with no elements at all (the empty set)!
The union of a collection of sets is defined as the set of all distinct elements that are in the collection. This includes the specific case where the collection consists of two sets.
The union of sets A and B, that is, the set of all elements that are either in A or B (or both).
The union of two sets A and B is a set that consists of all elements which are either in A, or in B or in both.
The set of elements that are elements of the two (or more) given sets is called the intersection of the sets.
That's not true. All sets have zero or more elements. You can have a set with zero elements - the "empty set".
Basically two ways: either by listing all the elements, or by specifying some rule for elements to be included. Listing all the elements only makes sense for finite sets.
This set is known as the union of two or more sets, which comprises all unique elements that are present in at least one of the sets. These elements are shared between the sets and are not duplicated within the union set.
A set is a collection of well defined objects known as elements Opperatons of sets are 1)union - the union of sets A and B is the set that contains all elements in A and all elements in B. intersection - given two sets A and B, the intersection of A and B is a set that contains all elements in common between A and B. compliments - given set A, A compliment is the set of all elements in the universal set but not in A difference - A-B is a set containing all elements in A that are not in B. symmetric difference - it is the sum of A and B minus A intersection B.
The union of two sets, X and Y, is the set containing all the elements that are either in X or in Y or in both. Duplicate entries are usually removed.
For example, if you take the set A = {1, 2}, then the following sets are all subsets of it: {}, {1}, {2}, {1, 2}. That is, all the sets that fulfill the condition that all of its elements are also elements of the set "A".
You can specify a set either by listing all of its members (not an option for sets that are very large or even infinite), or by specifying some rule for elements to be a part of the set.
Allowing sets with zero elements simplifies things, in the sense of not requiring all sorts of special cases. For example: the intersection of two sets is another set (which contains all items that are elements of BOTH original sets). Period! If you allow the empty set, there is no need to alter the definition of an intersection, to consider the special case that the sets have no elements in common.
