Example: x ≤ 2 or x >3

We used a “U” to mean Union (the joining together of two sets).

## What does the U mean in math?

## What does ∩ mean?

Definition of Intersection of Sets: Intersection of two given sets is the largest set which contains all the elements that are common to both the sets. The symbol for denoting intersection of sets is ‘∩’.

## What does the U mean in probability?

U(a,b) uniform distribution. equal probability in range a,b.

## What does U mean in Venn diagrams?

Each circle or ellipse represents a category. The union of two sets is represented by ∪. (Don’t confuse this symbol with the letter “u.”) The complete Venn diagram represents the union of A and B, or A ∪ B. Feel free to click on the image to try this diagram as a template.

## What does a ∩ B mean?

In mathematics, the intersection of two sets A and B, denoted by A ∩ B, is the set containing all elements of A that also belong to B (or equivalently, all elements of B that also belong to A).

## What does ∩ mean in statistics?

P(A ∩ B) refers to the probability of the intersection of events A and B. P(A ∪ B) refers to the probability of the union of events A and B. E(X) refers to the expected value of random variable X.

## What does C mean in math?

In math, generally you see that as the set of all complex numbers. In addition to PreCalculus, C is a one number in the Mean Value Theorem or (MVT) for short.

## Is there a symbol for opposite?
