## What does U and upside down U mean in math?

Union and Intersection We just saw how to join two sets using “Union” (and the symbol ∪). There is also “Intersection” which means “has to be in both”. Think “where do they overlap?”. The Intersection symbol is an upside down “U” like this: ∩

## What is the U symbol 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}.

## What is the upside down U in probability?

## What does ∩ mean in statistics?

A ∩ B refers to the intersection of events A and B. A ∪ B refers to the union of events A and B. {A, B, C} refers to the set of elements consisting of A, B, and C.

## What does U mean in stats?
