expected value (E(X)) of a random variable is also the mean of a probability distribution. The expected value for any discrete random variable can be calculated in the following manner: E(X) = = x P(x). The . variance. of a discrete random variable can be found using the following formula: 2 = x2P(x) – 2. The Binomial Distribution is the ...

The expected value does not have to be a possible value of the r.v. --- it’s an average value. Variance of a Discrete Random Variable The variance 2 is the expected value of the squared deviations from the mean ; that is, 2 = E[(X – )2].

The expected value of a discrete random variable X is denoted and defined by = E(X) = xiP(X=xi), where the sum is taken over all possible values xi. It is interpreted as the long-term average value that would result if the process were repeated over and over. Example 2: Roulette.
