Subject 6. Expected Value, Variance, and Standard Deviation of a Random Variable interpret expected value is as follows: If a number of such concerts were held, the organizers can expect to achieve a profit of $14,000 for each concert. So expected values actually make more sense when viewed over the long run.
<span>The variance of a random variable is the expected value (the probability-weighted average) of squared deviations from the random variable's expected value.
σ 2 (X) = E{[X - E(X)] 2 }
Variance is a number greater than or equal to 0.
If it is 0, there is no dispersion or risk. The outcome
