The expected value of an experiment is the probability-weighted average of all possible values. It is defined mathematically as follows:[br][center][math]E\left[X\right]=\sum_{x\in X}x\cdot P\left(x\right)[/math][/center]The law of large numbers states that the average result from a series of trials will converge to the expected value.[br][b][br]Roll the dice[/b] to see convergence to its expected value or click in [b]Simulation[/b].
