## What does the word given mean in probability?

So we have to say which one we want, and use the symbol “|” to mean “given”: P(B|A) means “Event B given Event A” In other words, event A has already happened, now what is the chance of event B.

P(B|A) is also called the “Conditional Probability” of B given A..

## What does V stand for in statistics?

maximum likelihood estimator of varianceIf h(x, y) = (x − y)2/2, the corresponding V-statistic is which is the maximum likelihood estimator of variance. With the same kernel, the corresponding U-statistic is the (unbiased) sample variance: .

## What does N mean in math?

List of Mathematical Symbols • R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers. Page 1. List of Mathematical Symbols. • R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.

## What words mean multiply?

The Basic OperationsSymbolWords Used+Addition, Add, Sum, Plus, Increase, Total−Subtraction, Subtract, Minus, Less, Difference, Decrease, Take Away, Deduct×Multiplication, Multiply, Product, By, Times, Lots Of÷Division, Divide, Quotient, Goes Into, How Many Times

## 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 does U mean in probability?

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

## What is the and/or rule in probability?

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.

## Does and mean add or multiply?

In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem. … Here is another example of a multiplication fact that shows multiplication is also repeated addition.

## What is a ∆ B?

A∆B which is called the symmetric difference between A and B is defined as (A-B)U(B-A). Now, A-B is the set of all elements which are in A but not in B. So, A – B = {1,2}. Similarly, B-A is the set of all elements which are in B but not in A.

## How do I know if I add or multiply probabilities?

But the probability that either event will occur (A or B) is typically found by adding: When you’re looking for the probability that two events, A andB, will BOTH occur, the probability of this coincidence is small, and you multiply the separate probabilities of A and B to get a smaller number.

## Does Per mean to multiply?

Multiplication-product, multiply, multiplied by, times. Division-quotient, dividend, divide, divided by, each, per, average, divided equally. Equal-the same, equals, the same as, equivalent, is equal to. *Remember these words when working on word problems to help set up.

## What is the U symbol in math?

In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other.

## What does or mean in probability and statistics?

Probability theory indicates the probability of either event A or event B occurring (“or” in this case means one or the other or both).

## 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).

## What are the 5 rules of probability?

Basic Probability RulesProbability Rule One (For any event A, 0 ≤ P(A) ≤ 1)Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)Probability Rule Three (The Complement Rule)Probabilities Involving Multiple Events.Probability Rule Four (Addition Rule for Disjoint Events)Finding P(A and B) using Logic.More items…

## What does ∩ mean in probability?

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)

## Does U MEAN AND or OR in math?

So the union of sets A and B is the set of elements in A, or B, or both. …
