Conceptually, the variance of a discrete random variable is the sum of the difference between each value and the mean times the probility of obtaining that value, as seen in the conceptual formulas below:. What is the EV of your gain? Your explanations on here are clear cut and easy to follow. Select the Correct Variable Type.

The property can be proved only using the Lebesgue integral see the lecture entitled Expected value and the Lebesgue integral. Since your list of outcomes should represent all the possibilities, the sum of probabilities should equal 1.

What from this follows?
