Against the odds

Planning a visit to Melbourne's Crown Casino? You may want to avoid their $2.50 roulette tables where they've just doubled the house's chance of winning by adding an extra 0. According to The Daily Telegraph, the addition of 00 to the wheels, which also retain the 0, has doubled the house's chances. If I was more into the science of odds - or knew my roulette table better (I know you've tried M) - I could tell whether the punter's chances have gone from 1 in 37 to 1 in 38, or something else entirely.
