Maria has a book, which she is considering selling. Is Maria making a profit? The answer is no. Jenny is trying to determine which store front she should purchase to expand her retail chain.

She did some research to determine how much profit she could earn at each store. In other words, it is a value determined by taking all potential results, multiplying each one by how likely it is to occur, and adding them together.

The sum of these numbers is the EV. Search for:. Soon enough they both independently came up with a solution. They solved the problem in different computational ways, but their results were identical because their computations were based on the same fundamental principle.

The principle is that the value of a future gain should be directly proportional to the chance of getting it. This principle seemed to have come naturally to both of them.

They were very pleased by the fact that they had found essentially the same solution, and this in turn made them absolutely convinced they had solved the problem conclusively; however, they did not publish their findings.

They only informed a small circle of mutual scientific friends in Paris about it. In this book, he considered the problem of points, and presented a solution based on the same principle as the solutions of Pascal and Fermat.

Huygens also extended the concept of expectation by adding rules for how to calculate expectations in more complicated situations than the original problem e.

In this sense, this book can be seen as the first successful attempt at laying down the foundations of the theory of probability.

It should be said, also, that for some time some of the best mathematicians of France have occupied themselves with this kind of calculus so that no one should attribute to me the honour of the first invention.

This does not belong to me. But these savants, although they put each other to the test by proposing to each other many questions difficult to solve, have hidden their methods.

I have had therefore to examine and go deeply for myself into this matter by beginning with the elements, and it is impossible for me for this reason to affirm that I have even started from the same principle.

But finally I have found that my answers in many cases do not differ from theirs. Neither Pascal nor Huygens used the term "expectation" in its modern sense.

In particular, Huygens writes: . That any one Chance or Expectation to win any thing is worth just such a Sum, as wou'd procure in the same Chance and Expectation at a fair Lay.

This division is the only equitable one when all strange circumstances are eliminated; because an equal degree of probability gives an equal right for the sum hoped for.

We will call this advantage mathematical hope. Whitworth in Intuitively, the expectation of a random variable taking values in a countable set of outcomes is defined analogously as the weighted sum of the outcome values, where the weights correspond to the probabilities of realizing that value.

However, convergence issues associated with the infinite sum necessitate a more careful definition. A rigorous definition first defines expectation of a non-negative random variable, and then adapts it to general random variables.

Unlike the finite case, the expectation here can be equal to infinity, if the infinite sum above increases without bound. By definition,. A random variable that has the Cauchy distribution  has a density function, but the expected value is undefined since the distribution has large "tails".

The basic properties below and their names in bold replicate or follow immediately from those of Lebesgue integral. Note that the letters "a.

We have. Changing summation order, from row-by-row to column-by-column, gives us. The expectation of a random variable plays an important role in a variety of contexts.

For example, in decision theory , an agent making an optimal choice in the context of incomplete information is often assumed to maximize the expected value of their utility function.

For a different example, in statistics , where one seeks estimates for unknown parameters based on available data, the estimate itself is a random variable.

In such settings, a desirable criterion for a "good" estimator is that it is unbiased ; that is, the expected value of the estimate is equal to the true value of the underlying parameter.

It is possible to construct an expected value equal to the probability of an event, by taking the expectation of an indicator function that is one if the event has occurred and zero otherwise.

This relationship can be used to translate properties of expected values into properties of probabilities, e.

The moments of some random variables can be used to specify their distributions, via their moment generating functions.

To empirically estimate the expected value of a random variable, one repeatedly measures observations of the variable and computes the arithmetic mean of the results.

If the expected value exists, this procedure estimates the true expected value in an unbiased manner and has the property of minimizing the sum of the squares of the residuals the sum of the squared differences between the observations and the estimate.

The law of large numbers demonstrates under fairly mild conditions that, as the size of the sample gets larger, the variance of this estimate gets smaller.

This property is often exploited in a wide variety of applications, including general problems of statistical estimation and machine learning , to estimate probabilistic quantities of interest via Monte Carlo methods , since most quantities of interest can be written in terms of expectation, e.

Es wird immer einfacher, zu vergleichen. Unser Gegner ist beide Male lediglich mitgegangen. Pokeranfänger werden zu Beginn oft mit mathematischen Begriffen überschüttet und Erwartungswert ist zweifelsohne einer davon. Wir sagen, dass die Quote ist.

In classical mechanics , the center of mass is an analogous concept to expectation. For example, suppose X is a discrete random variable with values x i and corresponding probabilities p i.

Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i whose sum is one.

The point at which the rod balances is E[ X ]. Expected values can also be used to compute the variance , by means of the computational formula for the variance.

A very important application of the expectation value is in the field of quantum mechanics. Thus, one cannot interchange limits and expectation, without additional conditions on the random variables.

A number of convergence results specify exact conditions which allow one to interchange limits and expectations, as specified below.

There are a number of inequalities involving the expected values of functions of random variables.

The following list includes some of the more basic ones. From Wikipedia, the free encyclopedia. Long-run average value of a random variable.

In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values.

By calculating expected values, investors can choose the scenario most likely to give the desired outcome.

Scenario analysis is one technique for calculating the expected value EV of an investment opportunity. It uses estimated probabilities with multivariate models to examine possible outcomes for a proposed investment.

Scenario analysis also helps investors determine whether they are taking on an appropriate level of risk given the likely outcome of the investment.

The EV of a random variable gives a measure of the center of the distribution of the variable. Essentially, the EV is the long-term average value of the variable.

Because of the law of large numbers , the average value of the variable converges to the EV as the number of repetitions approaches infinity.

The EV is also known as expectation, the mean or the first moment. EV can be calculated for single discrete variables, single continuous variables, multiple discrete variables, and multiple continuous variables.

For continuous variable situations, integrals must be used. To calculate the EV for a single discrete random variable, you must multiply the value of the variable by the probability of that value occurring.

Take, for example, a normal six-sided die. Once you roll the die, it has an equal one-sixth chance of landing on one, two, three, four, five, or six.

Given this information, the calculation is straightforward:. If you were to roll a six-sided die an infinite amount of times, you see the average value equals 3.
