## What does the E symbol mean in algebra?

∈ (mathematics) means that it is an element in the set of… … x ∈ ℕ denotes that x is within the set of natural numbers. The relation “is an element of”, also called set membership, is denoted by the symbol “∈”.

## What does P A upside down UB mean?

It means the Intersection of a set. For example, IF you have a set of even numbers and a set of odd numbers, the Union ‘U’ of these two sets would be ALL numbers. But, the Intersection (upside down U) would mean that NONE of the numbers in Evens are in common with any of the Odds in the second set.

## What is a ∆ B?

A ∆ B = {1,2,9,14} A⊖B. symmetric difference. objects that belong to A or B but not to their intersection.

## How do you type an upside down V?

## What does ∩ mean in probability?

The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B)

## What is the symbol for empty set?

symbol ∅Empty Set: The empty set (or null set) is a set that has no members. Notation: The symbol ∅ is used to represent the empty set, { }. Note: {∅} does not symbolize the empty set; it represents a set that contains an empty set as an element and hence has a cardinality of one.

## What is a ∆ B in sets?

The symmetric difference of two sets A and B is the set (A – B) ∪ (B – A) and is denoted by A △ B. … A △ B is the set of all those elements which belongs either to A or to B but not to both.

## What is a set symbol?

The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.

## What does U mean in stats?

The term population mean, which is the average score of the population on a given variable, is represented by: μ = ( Σ Xi ) / N. 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.
