Taking several factors into account:
Depending on the dealer draws one game or another, you have to detect what game he is doing according to the numbers he is drawing and try to predict them.
These are some examples but there are more. Could someone give me a hand?

How about simulation? Create a function that has all these rules you are taking about (If(number ==11, do xyz)) and then just call it miillions of times with a new random number every time (Random integer(1, 100).).
That was my thought too, when I read the question. But it appears that (I've only seen this game in Bond movies...)
There is nothing interesting here...
Unless you believe there is a way for the dealer to affect the outcome, which seems to be what the question is about. I'm pretty sure it would be possible to build a robotic dealer that could target half of the wheel with some degree >50% of accuracy. If I was a bored, minimum wage dealer, I'd almost certainly be trying to see if I could somehow do that. Then the question becomes "can I tell after 40 games (the first 20 minutes of a 30 minute run for a dealer) how to place a bet for the last 10 minutes?" because some of the multiple outcome bets do target sectors of the wheel.
The little bit of research I just did was kind of crazy. The site I wanted to reference had a section on monopole magnets, so I'll leave that out. I'm going to clear my cookies now.
