Although the concept of expected value is often used in the case of various multivariate models and scenario analysis, it is predominantly used in the calculation of expected return.

This has been a guide to the Expected Value Formula. Here we learn how to calculate the expected value along with examples and downloadable excel template.

Formula to Calculate Expected Value Expected value formula is used in order to calculate the average long-run value of the random variables available and according to the formula the probability of all the random values is multiplied by the respective probable random value and all the resultants are added together to derive the expected value.

Popular Course in this category. 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:.

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.
