Calculating the expected value of X involves multiplying each possible value of X by its probability of occurrence, then summing up all these values. This calculation helps in understanding the average outcome of an uncertain situation.<\/p>\n

The formula to calculate the expected value of X can be represented as: E(X) = \u03a3 (x * P(x)), where x represents the possible values of X, and P(x) represents the probability of each corresponding value.<\/p>\n

For example, suppose you are playing a dice game where rolling a 1 gives you $1, rolling a 2 gives you $2, and so on. The expected value of your winnings can be calculated as E(X) = (1 * 1\/6) + (2 * 1\/6) + (3 * 1\/6) + (4 * 1\/6) + (5 * 1\/6) + (6 * 1\/6) = $3.50.<\/p>\n
