odds of random events : constant or dependent on amount ? (temple kill event etc. )

[Agrajag]

As far as I understand you have a chance of (hypotheticaly speaking) 5% of an event happening in each one of your provinces.
Those 5% are then modified by the scales in action in the province (more for turmoil etc.).
After it has been decided if you recieve an event or not and in case you are, the luck scales in that province are then consulted to see wether you get a good or bad event.
So to have a high chance of a good event happening in a certain province, the scales in that province have to be on the side of luck (preferably +3).
Enemy dominions can mess your luck up in certain provinces, so to get the full effect of the +3 luck you are going to have to have your dominion in your provinces.
Hope that makes sense and wasn't just stating the obvious.
