# The expected value

The expected value (or mean) of X, where X is a discrete random variable, is a weighted average of the possible values that X can take, each value being. In probability and statistics, the expectation or expected value, is the weighted average value of a random variable. In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents. For example Definition · General definition · Properties · Uses and applications.
Denote the absolute value of a random variable by. The convergence is relatively slow: Adding 3 and 4 gives us the expected value: The concept of expected value of a random variable is one of the most important concepts in probability theory. Online casino tropez-betrug such information can influence you decision on whether to play. When summing infinitely many terms, the order in which you sum them can change the result of the sum.

You are absolutely right. In it something is and it is good thought. It is ready to support you.
