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.
Is the set of nonregular languages closed under intersection?
No, the set of nonregular languages is not closed under intersection.
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.
What is the intersection of the set of rational numbers and the set of irrational number?
Its a null set.
What is the intersection set?
is the result after doing intersection on 2 or more sets. It contains the elements which are common to all the sets on which intersection were done.
How will you write using the venn diagram the union of set a(1234) and the intersection of set b(10111213) and set c(1213)?
If B = {10111213} and C = {1213} then their intersection is the empty set, {}.The union of A with an empty set is set A.
Is the intersection of two infinite sets always an infinite set?
No. It can be infinite, finite or null. The set of odd integers is infinite, the set of even integers is infinite. Their intersection is void, or the null set.
What does intersection mean mathiticaly?
The intersection is the set of solutions that satisfy two or more mathematical expressions.
Do sets always have an intersection that is not the empty set?
No, they do not.
Is intersection of two countably infinite sets can be finite?
Easily. Indeed, it might be empty. Consider the set of positive odd numbers, and the set of positive even numbers. Both are countably infinite, but their intersection is the empty set. For a non-empty intersection, consider the set of positive odd numbers, and 2, and the set of positive even numbers. Both are still countably infinite, but their intersection is {2}.
Is the intersection of the set of rational numbers and the set of whole numbers is the set of rational numbers?
No, it is not.
What is the symbol of intersection?
In set theory, the symbol of intersection is ∩, like an upside down U.
