Expectation formula
In probability theory, the conditional expectation, conditional expected value, or conditional ... All the following formulas are to be understood in an almost sure sense. The σ-algebra H -displaystyle -mathcal H}}} -mathcal H}} could be ... ,The expected value of X is usually written as E(X) or m. So the expected value is the sum of: [(each of the possible outcomes) × (the probability of the outcome occurring)]. In more concrete terms, the expectation is what you would expect the outcome of a
