What does math union symbol mean?
The union symbol ( ) denotes the union of two set s. It is commonly used in mathematics and engineering. Given two sets A and B, the union of A and B, written A B, is the set C of all elements that are in A or in B.
What does ∩ and ∪ mean in math?
∪ The symbol ∪ means union. Given two sets S and T, S ∪ T is used to denote the set {x|x ∈ S or x ∈ T}. For example {1,2,3}∪{3,4,5} = {1,2,3,4,5}. ∩ The symbol ∩ means intersection. Given two sets S and T, S ∩ T is used to denote the set {x|x ∈ S and x ∈ T}.
What is union math example?
The union of two sets is a set containing all elements that are in A or in B (possibly both). For example, {1,2}∪{2,3}={1,2,3}.
What does ∩ mean in math sets?
The intersection operation is denoted by the symbol ∩. The set A ∩ B—read “A intersection B” or “the intersection of A and B”—is defined as the set composed of all elements that belong to both A and B.
What does ∪ mean in probability?
union
The symbol “∪” (union) means “or”. i.e., P(A∪B) is the probability of happening of the event A or B. To find, P(A∪B), we have to count the sample points that are present in both A and B.
What do you mean by union?

(Entry 1 of 2) 1a : an act or instance of uniting or joining two or more things into one: such as. (1) : the formation of a single political unit from two or more separate and independent units. (2) : a uniting in marriage also : sexual intercourse. (3) : the growing together of severed parts.
What does a ∩ B mean?
A intersection B
The set A ∩ B—read “A intersection B” or “the intersection of A and B”—is defined as the set composed of all elements that belong to both A and B. Thus, the intersection of the two committees in the foregoing example is the set consisting of Blanshard and Hixon.
What is a ∪ B?
The union of two sets A and B is a set that contains all the elements of A and B and is denoted by A U B (which can be read as “A or B” (or) “A union B”). A union B formula is used to find the union of two sets A and B.
What is a ∩ C?
A intersection B intersection C represents the common elements of the sets A, B, and C respectively. This is generally represented as A n B n C. The symbol ‘n’ represents intersection and gives the common element of the two sets.
What is a ∩ B ∩ C?
The intersection of two sets A and B ( denoted by A∩B ) is the set of all elements that is common to both A and B. In mathematical form, For two sets A and B, A∩B = { x: x∈A and x∈B } Similarly for three sets A, B and C, A∩B∩C = { x: x∈A and x∈B and x∈C }
Who does the union represent?
