WebbExpected Value In a probability distribution , the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value , usually represented by E ( x ) . The expected value informs about what to expect in an experiment "in the long run", after many trials. Webb24 apr. 2024 · As noted above, here is the measure-theoretic definition: If X is a real-valued random variable on the probability space, the expected value of X is defined as the integral of X with respect to P, assuming that the integral exists: E(X) = ∫ΩXdP Let's review how the integral is defined in stages, but now using the notation of probability theory.
