Explanation:

  • The expected value of a discrete random variable is a measure of the central tendency of the variable.

  • It is denoted by E(x) and is defined as the sum of products of the different values and the corresponding probabilities.

  • Mathematically, E(x) = Σ (x * P(x)), where x is a possible value of the discrete random variable and P(x) is the probability of x.

  • For example, if we have a discrete random variable X that can take values 1, 2, 3, and 4 with probabilities 0.1, 0.2, 0.3, and 0.4 respectively, then the expected value of X can be calculated as follows:


    • E(X) = (1 * 0.1) + (2 * 0.2) + (3 * 0.3) + (4 * 0.4)

    • E(X) = 0.1 + 0.4 + 0.9 + 1.6

    • E(X) = 3


  • Therefore, in this case, the expected value of X is 3.

  • The expected value of a discrete random variable can also be interpreted as the long-run average value of the variable.

  • It is an important concept in probability theory and has many applications in various fields such as economics, finance, and engineering.
