Der Erwartungswert, der oft mit abgekürzt wird, ist ein Grundbegriff der Stochastik. Der Erwartungswert einer Zufallsvariablen beschreibt die Zahl, die die Zufallsvariable im Mittel annimmt. Er ergibt sich zum Beispiel bei unbegrenzter.

To find the expected value of a game that has outcomes x 1 , x 2 ,. Why 8 and not 10? This means that over the long run, you should expect to lose on average about 33 cents each time you play this game.

Yes, you will win sometimes. But you will lose more often. Now suppose that the carnival game has been modified slightly.

In the long run, you won't lose any money, but you won't win any. Don't expect to see a game with these numbers at your local carnival.

If in the long run, you won't lose any money, then the carnival won't make any. Now turn to the casino. In the same way as before we can calculate the expected value of games of chance such as roulette.

In the U. Half of the are red, half are black. Both 0 and 00 are green. A ball randomly lands in one of the slots, and bets are placed on where the ball will land.

One of the simplest bets is to wager on red. If the ball lands on a black or green space in the wheel, then you win nothing.

What is the expected value on a bet such as this? 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:. The formula for expected value is simple as it could be, the probability distribution is multiplied by the outcomes and all total is added to arrive at the expected value.

To explain this, according to the above information, the expected number of days that you will head to the gym is roughly two days a week.

As per the calculation, it is 1. This helps in understanding that even though the distribution of days attending the gym might not be constant but the rough estimate can be realized.

Here we discuss formula to calculate the expected value along with some examples, advantages, and disadvantages. You can learn more about excel modeling from the following articles —.
