What does a vertical line mean in probability?

The vertical bar is often called a ‘pipe’.

It is often used in mathematics, logic and statistics.

It typically is read as ‘given that’.

In probability and statistics it often indicates conditional probability, but can also indicate a conditional distribution.

You can read it as ‘conditional on’..

What is a vertical line called on a graph?

Ordinate – The vertical line, or y-axis, of a graph.

What does at least mean in probability?

• all probabilities larger than the given probability (“at least”) • all probabilities smaller than the given probability (“at most”) The probability of an event, p, occurring exactly r times: n = number of trials.

What is the difference between probability and prediction?

Understanding the difference between a prediction and the probability of a particular outcome occurring is an important distinction for successful investors. … Predictions are absolute, right or wrong. Probabilities run a spectrum, from highly unlikely to extremely likely.

What does the line symbol mean in probability?

= P(A) • P(B|A) or P(B)*P(A|B) Note: this straight line symbol, |, does not mean divide! This symbols means “conditional” or “given”. For instance P(A|B) means the probability that event A occurs given event B has occurred.

What does vertical line mean in maths?

Vertical lines in math In math, the y-axis is considered vertical. Hence any line parallel to the y-axis is a vertical line. Also, vertical lines are perpendicular to the x-axis.

What is vertical line symbol called?

The vertical line, also called the vertical slash or upright slash ( | ), is used in mathematical notation in place of the expression “such that” or “it is true that.” This symbol is commonly encountered in statements involving logic and sets. Also see Mathematical Symbols.

What does C in math mean?

the set of all complex numbersIt means “the set of all complex numbers” or “in the complex numbers”.

What does upside down U mean in probability?

Union and Intersection 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 does AUB mean 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)

What is the OR rule?

Sometimes we want to know the probability of getting one result or another. When events are mutually exclusive and we want to know the probability of getting one event OR another, then we can use the OR rule. … P(A or B) = P(A) + P(B) for mutually exclusive events.

What does or mean in probability?

In probability, there’s a very important distinction between the words and and or. And means that the outcome has to satisfy both conditions at the same time. Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time.
