Fact file
Tabcorp take bets on which two teams in the final eight will play off for the Grand Final. At one stage many years ago now they were accepting bets on combinations that were mathematically impossible. (Certain teams on the same side of the draw cannot meet in the Grand Final because they would have to meet each other in an elimination match before they could get to that stage.)
The practice was stopped after it was pointed out to them by our own Professor Stephen Clarke and a small article about the practice appeared in the Age newspaper. Amusingly, the odds offered on the impossible combinations were actually tighter than those offered on some other combinations!
