Once a zero has been spun, the chance that the other 36 numbers will come in 36 spins is 1 in 760 trillion (US trillions). Given the number of roulette wheels that have been spun around the world every day for decades, the chances are that it has happened.
Your first sentence is spot on. However, buying 2 tickles in a raffle DOES halve your odds of winning. If you buy 2 tickets in your 120 ticket raffle then you have a 2/120 chance of winning; that's the same as 1/60.
I work in risk assessment and so calculate probability daily. I can confirm that buying 2 tickets, each with a probability of winning of 1/112 000 000, gives an overall probability of 2/112 000 000 - or 1/56 000 000.
Well good luck to you. But don't come on to thread started by a naive bloke who's admitting a gambling problem and say that a game of chance can be beaten. You're kidding yourself - as was the bloke who told you - if you think you can predict the numbers where there are so many random variables...
