Example of Expected Value (EV) 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… For example, compare a high-deductible versus

Let’s say a ticket costs $10, and you have a 0.0000001 chance of winning $10 million dollars — should you buy one? Note that +425,000 dollars is a statistical term; it means the average of +425,000 dollars will be achieved in the long-term for drilling over and over again in a repeated investment of this type. The expected value or the population mean of a random variable indicates its central or average value.
Expected Value = 0.7 * (0 − 400, 000) + 0.25 * (2, 500, 000 − 400, 000) + 0.05 * (4, 000, 000 − 400, 000) = $ 425, 000. For instance, using the example you provided where there’s a 2/3 (66%) chance of winning $30 and 1/3 (33%) chance of losing $15, EV should be: 30 x .66 = 20 -15 x .33 = -5 20-5 = an Expected Value of 15. expected values.
