the odds for the next one. In random or chance events, each go

There is widespread belief in everyday life that luck will
somehow even out. The phrase 'third time lucky' is indicative of
a general feeling that after two failures the odds for success
improve. Not so. If the events are genuinely random, there is no

win. If, as is more common, the results reflect on the character
and competence of the performer, the two losses begin to
establish a basis for judgement.

chances of another ace being drawn are correspondingly
reduced. Professional gamblers are very good at remembering
which cards have been drawn already, and how this bears upon
forthcoming draws. Still other gamblers are very good at making
up from their sleeves what the laws of chance and probability
have denied them from the deck.
