Bwahahaha. Second gem in a row.
Dude, Google that word you are using - "probability" - and read some textbooks.
Yes, it's a fresh .001 chance every time. And it combines into a table that you replied "that is not how blizzard probability works" to. A paradox, right?
Apologies to those who want to discuss BMAH, I promise I will hold my hand next time. I agree it's pointless to talk and explain and re-explain the same math for the 20th time, there's always some new guy who is confused but thinks he isn't.
