Here the house has a slight edge as with all casino games. As another example, consider a lottery. This gives us an expected value of:.
So if you were to play the lottery over and over, in the long run, you lose about 92 cents — almost all of your ticket price — each time you play.
All of the above examples look at a discrete random variable. However, it is possible to define the expected value for a continuous random variable as well.
All that we must do in this case is to replace the summation in our formula with an integral. It is important to remember that the expected value is the average after many trials of a random process.
In the short term, the average of a random variable can vary significantly from the expected value. Share Flipboard Email. Courtney Taylor. Professor of Mathematics.

This advantage is so small that it can be difficult to detect, but in the end, the house always wins. Share Flipboard Email. Courtney Taylor.

Which seems very messy There must be something I am not understanding about the properties of expected values? It stops being random once you take one expected value, so iteration doesn't change.

Learn more Expected value EV is a concept employed in statistics to help decide how beneficial or harmful an action might be.
Knowing how to calculate expected value can be useful in numerical statistics, in gambling or other situations of probability, in stock market investing, or in many other situations that have a variety of outcomes.
To calculate an expected value, start by writing out all of the different possible outcomes. Then, determine the probability of each possible outcome and write them as a fraction.
Next, multiply each possible outcome by its probability. Finally, add up all of the products and convert your answer to a decimal to find the expected value.

Method 1 of Identify all possible outcomes. Calculating the expected value EV of a variety of possibilities is a statistical tool for determining the most likely result over time.
To begin, you must be able to identify what specific outcomes are possible. You should either list these or create a table to help define the results.
You need to list all possible outcomes, which are: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, in each of four different suits.
Assign a value to each possible outcome. Some expected value calculations will be based on money, as in stock investments. Others may be self-evident numerical values, which would be the case for many dice games.
In some cases, you may need to assign a value to some or all possible outcomes. Assign those values for this example. Determine the probability of each possible outcome.
Probability is the chance that each particular value or outcome may occur. In some situations, like the stock market, for example, probabilities may be affected by some external forces.
You would need to be provided with some additional information before you could calculate the probabilities in these examples.
In a problem of random chance, such as rolling dice or flipping coins, probability is defined as the percentage of a given outcome divided by the total number of possible outcomes.
However, recognize that there are four different suits, and there are, for example, multiple ways to draw a value of Since your list of outcomes should represent all the possibilities, the sum of probabilities should equal 1.
Multiply each value times its respective probability. Each possible outcome represents a portion of the total expected value for the problem or experiment that you are calculating.
To find the partial value due to each outcome, multiply the value of the outcome times its probability. Multiply the value of each card times its respective probability.
Find the sum of the products. The expected value EV of a set of outcomes is the sum of the individual products of the value times its probability.
Using whatever chart or table you have created to this point, add up the products, and the result will be the expected value for the problem. Interpret the result.
The EV applies best when you will be performing the described test or experiment over many, many times.
For example, EV applies well to gambling situations to describe expected results for thousands of gamblers per day, repeated day after day after day.
However, the EV does not very accurately predict one particular outcome on one specific test. Over many many draws, the theoretical value to expect is 6.
But if you were gambling, you would expect to draw a card higher than 6 more often than not. Method 2 of Define all possible outcomes. Calculating EV is a very useful tool in investments and stock market predictions.
As with any EV problem, you must begin by defining all possible outcomes. Generally, real world situations are not as easily definable as something like rolling dice or drawing cards.
For that reason, analysts will create models that approximate stock market situations and use those models for their predictions.
These results are: 1. Earn an amount equal to your investment 2. Earn back half your investment 3. Neither gain nor lose 4. Lose your entire investment.
Assign values to each possible outcome. In some cases, you may be able to assign a specific dollar value to the possible outcomes. Other times, in the case of a model, you may need to assign a value or score that represents monetary amounts.
The assigned value of each outcome will be positive if you expect to earn money and negative if you expect to lose. Determine the probability of each outcome.
