Let be an absolutely continuous random variable. Expectation of continuous random variable E X is the expectation value of the continuous random variable X x is the value of the continuous random variable X P x is the probability density function Expectation of discrete random variable E X is the expectation value of the continuous random variable X x is the value of the continuous random variable X P x is the probability mass function of X Properties of expectation Linearity When a is constant and X,Y are random variables: Since your list of outcomes should represent all the possibilities, the sum of probabilities should equal 1. We will fill in the rest of the information into the expected values table. You toss a fair coin three times. For that reason, analysts will create models that approximate stock market situations and use those models for their predictions. Two dice are thrown simultaneously.
