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.

Related Terms Random Variable A random variable is a variable whose value is unknown, or a function that assigns values to each of an experiment's outcomes.
The expected value is comprised on two components: how much you can expect to gain, and how much you can expect to lose.
Draw or sketch a two-row probability chart. The probability chart should be two rows wide and two columns deep. Label the first row "Gain" and the second row "Probability.
Work out how much money you could win or lose. Write your odds of winning on the bottom row. Place this at the bottom left of the probability chart.
Write your odds of losing on the bottom row. Multiply the figure at the top of each column by the figure at the bottom of each column. In the above example, the calculations for the expected values are:.
Add all of the values together to compute the expected value.
