The union of two or more sets is a set containing all of the members in those sets. For example, the union of sets with members 1, 2, 3, and a set with members 3, 4, 5 is the set with members 1, 2, 3, 4, 5. So we can write:
Let A = {1. 2. 3} and B = {3, 4, 5}, then
A∪B = {1, 2, 3, 4, 5}
The intersection of two or more sets is the set containing only the members contained in every set. For example, the intersection of a set with members 1, 2, 3, and a set with members 3, 4, 5 is the set with only member 3. So we can write:
Let A = {1. 2. 3} and B = {3, 4, 5}, then
A ∩ B = {3}

Difference between Union and Set Intersection Operation?
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.
How do you use venn diagram to represent the union and intersection sets?
For two sets, the Venn diagram will consist of two overlapping ovals. The area of the overlap is the intersection. The entire area of both ovals is the union.
What are intersection sets and union sets?
Sets contain elements. The intersection of sets (represented by an upside-down 'U') is the list of elements that are common in both sets. The union of sets (represented by 'U') is the list of all the elements in the relevant sets. E.g. If A={a,b,c,d,e,f} and B={a,e,i,o,u}: The intersection of A and B is {a,e}. The union of A and B is {a,b,c,d,e,f,i,o,u} (notice how repeating elements, e.g. 'a' and 'e', are only listed once even though they occur in both sets.)
Do sets always have an intersection that is not the empty set?
No, they do not.
What are the closure properties of regular sets?
;: Th. Closed under union, concatenation, and Kleene closure. ;: Th. Closed under complementation: If L is regular, then is regular. ;: Th. Intersection: .
Do the intersection of two sets always contains a smaller number of terms than the union of two sets?
No, because the intersection of two equivalent sets will have a union the same size as its intersection.
Is there any case when union and intersection are same in sets?
if we have set A and B consider A={1,2,3,4}and B={3,4,5,6} the union of these sets is A and B={1,2,3,4,5,6}and the intersection is{3,4} the union and the intersection are same only if A=B
What is the union intersection set?
Given two or more sets there is a set which is their union and a set which is there intersection. But, there is no such thing as a "union intersection set", as required for the answer to the question.
What are the different sets operations?
Union, Intersection and Complement.
What are operations of sets?
union of sets,intersection of sets,difference of sets,ordered pair,ordered n-touples,cartician product of setThe basic operations are union and intersection. The complement of the set is also a basic operation.
Difference between Union and Set Intersection Operation?
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.
Intersection and union of sets of real numbers?
Yes, they can be very useful mathematical sets.
BASIC OPERATION ON sets in college algebra?
The basic operations on sets are union, intersection, complement.
What are the basic operations for sets in math?
The basic operations are union and intersection.
How do you use venn diagram to represent the union and intersection sets?
For two sets, the Venn diagram will consist of two overlapping ovals. The area of the overlap is the intersection. The entire area of both ovals is the union.
What is union and intersection of sets?
Given any two sets, for instance, A={ai} and B={bi}, the union of the sets are the values that are contained in either A orB, whereas the intersection of the sets are the values that are contained in both A and B.For instance, let A={1, 2, 4, 6, 9, 12} and B={1, 5, 7, 9, 11, 15}, then the union would be A∪B={1, 2, 4, 5, 6, 7, 9, 11, 12, 15} and the intersection would be A∩B={1, 9}.
Why empty set is a set?
The concept of closure: If A and B are sets the intersection of sets is a set. Then if the intersection of two sets is a set and that set could be empty but still a set. The same for union, a set A union set Null is a set by closure,and is the set A.
