Extraordinarily improbable events are commonplace. This is not a contradiction, but is the consequence of five laws, all based on sound mathematics. The laws are explained and illustrated with examples ranging from lightning strikes, lottery wins, financial crashes, and extrasensory perception experiments.
Coincidences happen, incredibly unlikely things occur, and the apparently miraculous comes about. The improbability principle says that such extraordinarily improbable events are commonplace. This is not a contradiction; we should expect identical lottery numbers to come up more than once, lightning to strike twice, and financial crashes to occur. David Hand introduces us to the five laws of probability theory that lead us to expect such improbable events to happen, and to keep on happening.
