The expected value of this scenario is: A very important application of the expectation value is in the field of quantum mechanics. This is a relatively simple gambling game. Analogously with the discrete case above, when a continuous random variable Calculation of expected value takes only non-negative values, we can use the following formula for computing its expectation even when the expectation is infinite:.
