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.
In a situation like the stock market, professional analysts spend their entire careers trying to determine the likelihood that any given stock will go up or down on any given day.
The probability of the outcomes usually depends on many external factors. Statisticians will work together with market analysts to assign reasonable probabilities to prediction models.
Multiply each outcome value by its respective probability. Use your list of all possible outcomes, and multiply each value times the probability of that value occurring.
Add together all the products. Find the EV for the given situation by adding together the products of value times probability, for all possible outcomes.
Interpret the results. You need to read the statistical calculation of the EV and make sense of it in real world terms, according to the problem.
Earning Method 3 of Familiarize yourself with the problem. Before thinking about all the possible outcomes and probabilities involved, make sure to understand the problem.
A 6-sided die is rolled once, and your cash winnings depend on the number rolled. Rolling any other number results in no payout.
This is a relatively simple gambling game. Because you are rolling one die, there are only six possible outcomes on any one roll.
They are 1, 2, 3, 4, 5 and 6. Assign a value to each outcome. This gambling game has asymmetric values assigned to the various rolls, according to the rules of the game.
For each possible roll of the die, assign the value to be the amount of money that you will either earn or lose.
In this game, you are presumably rolling a fair, six-sided die. Use the table of values you calculated for all six die rolls, and multiply each value times the probability of 0.
Calculate the sum of the products. Add together the six probability-value calculations to find the EV for the overall game. The EV for this gambling game is However, that luck is not going to continue if you keep playing.
You play a gambling game with a friend in which you roll a die. What is your expected value for this game? Not Helpful 3 Helpful Two dice are thrown simultaneously.
What is the probability of getting a sum less than 3? Each die would have to show "1" in order to get a sum less than 3. That means that only one outcome would be a desired outcome.
There are 36 possible outcomes 6 x 6. So the probability of a successful outcome is 1 in Not Helpful 3 Helpful 2.
A standard cubical die is thrown twice. How do I calculate the probability that two even numbers are thrown? The probability that the first throw will come up even is 3 in 6.
The probability that the second throw will come up even is also 3 in 6. The probability of throwing two even numbers is 1 in 4.
Not Helpful 5 Helpful 1. The mean is the average. Add the numbers together, and divide the sum by the number of numbers. Not Helpful 0 Helpful 0.
