Question

anonymous · Answer

true in probability theory, a long-run average can be said to follow the law of large numbers. This theorem describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed. http://en.wikipedia.org/wiki/Law_of_large_numbers
