Expected value of function of random variable
WebScalar multiplication a a random variably. Sums of irregular variables. Linear combinations of random variables. Expected assess of one constant. Expectation by a product of … WebThe expected value of a random variable is also interpreted as the long-run value of the random variable. In other words, if we repeat the underlying random experiment several times and take the average of the values of the random variable corresponding to the outcomes, we would get the expected value, approximately.
