The symbol that looks like a 0 with a line through it is the greek letter “theta”: θ. It is just a variable, you could as easily just call it x instead. For exponents, we usually type ^ (carat) in front.

## Do you put a line through a zero or an O?

Do not use a slash on a 0 or an O under any circumstances!!!! In old style computer printouts, the 0 had a slash through it, especially when it was part of a number. But a 0 with a slash through it looks like this: . And this is the symbol used to indicate the empty set, which is very, very, very different from 0.

## How do you get an O with a slash through it?

To type Slash O on Windows, Press and hold down the Alt key. While pressing down the Alt key, type 0216 using the numeric keypad to insert the symbol.

## What does ø mean in English?

Ø (or minuscule: ø) is a vowel and a letter used in the Danish, Norwegian, Faroese, and Southern Sami languages. The name of this letter is the same as the sound it represents (see usage). Though not its native name, among English-speaking typographers the symbol may be called a “slashed O” or “o with stroke”.

## How is the letter æ pronounced?

The pair ‘ae’ or the single mushed together symbol ‘æ’, is not pronounced as two separate vowels. It comes (almost always) from a borrowing from Latin. In the original Latin it is pronounced as /ai/ (in IPA) or to rhyme with the word ‘eye’. But, for whatever reason, it is usually pronounced as ‘/iy/’ or “ee”.

## What does circle with a slash mean?

Circle with slash means you tapped the volume button and then selected “None”. It means you are in silent mode.

## What does ø mean in sets?

The set Ø = is the empty set containing no elements. The set ℕ = 0, 1, 2, 3, 4, … is the set of all natural numbers. We treat 0 as a natural number.

## What does ø mean in Venn diagram?

intersection is empty

## What does a upside down UB mean?

intersection

## What is an upside down V called?

caret

## What does ∩ mean in probability?

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) = 0. The probability that Events A or B occur is the probability of the union of A and B.

## 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 is the mean of AB?

An ab is a stomach, or abdominal, muscle. Ab is shorthand for abdominal, which comes from the Latin abdomen, “belly,” and it’s a common name for what’s formally known as the rectus abdominus muscle. Your abs run up and down the front of your torso, on either side of your belly button.

## What are the elements of a ∩ B?

If A and B are sets, then A ∩ B, read “A intersection B”, is a new set. Its elements are those objects which are in A and in B i.e. those elements which are in both sets. Example If A = 1,2,3,4 and B = 2,4,6,8, list the elements of the set A ∩ B.

## Is A and B same as B and A?

Unless A and B are the same size and the same shape and have the same values in exactly the same places, they are not equal.

## What is different A and B?

Set Difference: The relative complement or set difference of sets A and B, denoted A – B, is the set of all elements in A that are not in B. Then the set difference of A and B would be the $407 remaining in the checking account. Example: Let A = a, b, c, d and B = b, d, e. Then A – B = a, c and B – A = e.

## What does equality mean in math?

In mathematics, equality is a relationship between two quantities or, more generally two mathematical expressions, asserting that the quantities have the same value, or that the expressions represent the same mathematical object.

## Is P and the same as P BnA?

I think you are talking about probability of occurrence of two events A, B from a sample space S, simultaneously. If so, then P(AnB) is same as P(BnA) always, in general.

## What does P ANB mean?

A ∩ B

## How do you solve P ANB?

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn’t affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

## How do you know if two events are independent?

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.
