expected value probability

The mean of a discrete probability distribution is all so know as the expected value. The expected value has. In this video, I show the formula of expected value, and compute the as a probability is since the zero. In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents. For example  ‎Conditional expectation · ‎Law of the unconscious · ‎Weighted arithmetic mean. Der bedingte Erwartungswert ist eine Verallgemeinerung des Erwartungswertes auf den Fall, dass Gewisse Ausgänge des Zufallsexperiments bereits bekannt sind. If you were to roll a six-sided die an infinite amount of times, you see the average value equals 3. I agree with the other post that it was hard to figure out at first, but after practicing over and over it finally came to me. For continuous variable situations, integrals must be used.
