probability wise upside down ‘U’ stands (A∩B) for A intersection of B means elements from both sets indicates are common from set A as well as set B. The symbol describes the Union of the two sets.∩ The symbol ∩ means intersection. Given two sets S and T, S ∩ T is used to denote the set {x|x ∈ S and x ∈ T}. For example {1,2,3}∩{3,4,5} = {3}. \ The symbol \ means remove from a set. Given two sets S and T, S\T is used to denote the set {x|x ∈ S and x /∈ T}.The union of a set A with a B is the set of elements that are in either set A or B. The union is denoted as A∪B.

What does the symbol ∩ represent?
∩: Intersection of two sets.
The intersection shows what items are shared between categories.
How do you use ∩?
The symbol used to denote the intersection of sets A and B is ∩, it is written as A∩B and read as ‘A intersection B’. The intersection of two or more sets is the set of elements that are common to every set. A∩B can be determined easily by checking the elements that are present in both A and B.
What does the U mean in probability?
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 is the U mean in statistics?
The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi‘ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on.
What does a ∪ B mean?
The symbol ∪ is employed to denote the union of two sets. Thus, the set A ∪ B—read “A union B” or “the union of A and B”—is defined as the set that consists of all elements belonging to either set A or set B (or both).

What does a sideways U mean in math?
A⊆B. The line under the sideways ∪ means that A may also be equal to B (that is, they may be identical sets). If we want to say that A is a proper subset of B (that means: it’s a subset, but there is at least one element in B that is not in A ) then we can remove the line: A⊂B.

- Mean (μ) = ΣX/N, where Σ is the summation (addition) sign, xi is each individual number, and N is the population size.
- In the case above, the mean μ is simply (12+55+74+79+90)/5 = 62.
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 AUB in probability?
P(A U B) is the probability of the sum of all sample points in A U B. Now P(A) + P(B) is the sum of probabilities of sample points in A and in B. Since we added up the sample points in (A ∩ B) twice, we need to subtract once to obtain the sum of probabilities in (A U B), which is P(A U B).
What does => mean in math?
It stands for “implies that“. For example, x=2⟹x2=4 – if x is 2, then it is obvious that x squared is 4; the symbol essentially shows a function here.
