The Lotto is a legal form of gambling in many states in which people attempt to predict (or guess) a set of numbers chosen randomly.

A large number of people have used this strategy in recent drawings of the Lotto, and their choices along with the winning numbers have been sent to a statistical consultant to determine if the strategy does indeed perform as advertised, but the statistical consultant has not yet done the analysis.
