In the realm of statistics, expectation refers to the predicted average result of a random event after numerous repetitions. This is computed by multiplying the likelihood of each potential outcome by the outcome itself, and then adding these results together. This essential principle in probability theory is frequently utilized in making decisions and forecasting future occurrences.
