What does a vertical line mean?

A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane. All points on the line will have the same x-coordinate. … A vertical line has no slope. Or put another way, for a vertical line the slope is undefined.

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.

What does the U symbol in probability mean?

2. P(A∪B) is the probability that the event is in A or B. For example, if your space of events is {1,2,3,4,5,6} (like throwing a dice), define A={1,2} and B={6}. In that case, P(A∪B) is the probability that the dice gives you 1,2 or 6. Therefore P(A∪B)=36=12=0.5=50%.

Is a straight vertical line a function?

For a relation to be a function, use the Vertical Line Test: Draw a vertical line anywhere on the graph, and if it never hits the graph more than once, it is a function. If your vertical line hits twice or more, it’s not a function.

What do the probability symbols mean?

The conditional probability of Event A, given Event B, is denoted by the symbol P(A|B). … 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) = 0.

What is the vertical line between words called?

The vertical bar, | , is a glyph with various uses in mathematics, computing, and typography. It has many names, often related to particular meanings: Sheffer stroke (in logic), pipe, vbar, stick, vertical line, vertical slash, bar, pike, or verti-bar, and several variants on these names.

What does the probability of 1 mean?

Chance is also known as probability, which is represented numerically. Probability as a number lies between 0 and 1 . A probability of 0 means that the event will not happen. A probability of 1 means that the event will happen. …

What does a vertical line mean in math?

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 line mean in probability?

Probability is the chance that something will happen. It can be shown on a line: The probability of an event occurring is somewhere between impossible and certain.

What does ∩ 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).

Can you have probability greater than 1?

Probabilities are measured over intervals, not single points. … This means that the height of the probability function can in fact be greater than one. The property that the integral must equal one is equivalent to the property for discrete distributions that the sum of all the probabilities must equal one.
