Webexpected value of a discrete random variable X, symbolized as E (X) long-term average or mean (symbolized as μ ). This means that over the long term of doing an experiment over and over, you would expect this average. For example, let X = the number of heads you get when you toss three fair coins. WebSuppose the probability mass function of the discrete random variable is . What is the value of E(3X + 2X 2) ? Solution . Example 6.19. Consider a random variable X with probability density function. Find E(X) and V(X). Solution. We know that, Example 6.20. If f (x) is defined by ( x) = ke − 2 x, 0 ≤ x < ∞ is a density function.
