TRUE Final Odds of Getting a Beta Key

Did anyone get a key yet?

Your math is correct but doesnt reflect the actual numbers. That is the chance of getting the last key if I dont get one of the 4999 ones. Remember there is going to be another 4999 rafles and they are all added to increase your chances. The actual chance is the sum of all the individual 5000 raffles. With every raffle you dont win a key your chances become slim till they get to that value you mathed.

To be more clear it works like this.

You have to math it out your chances of getting at least one key out of 5000 which is the oposite of not winning any of the 5000 raffles individually.

That math is 1 - (12799/12800)^5000 , of course this isnt correct either as everytime a key is chosen we have to decrease 1 from the total.

The devs will pick 5000 winners out of 12800 people, there are (12800 in 5000) ways to do that.

meaning the actual chances are 1 - (12800 in 5000) which are very close to the first one either way.

Which is less then what people are saying btw ( not much though) . Its 30~32%

Woah I got a key on my 2nd account. :o (I only have 2 btw, and I only made that other account because I thought FB linking was still broken lol)

But anyway, yay! :smile:

The final odds are…ZERO!! You dont get $&!/!!, said everyone that didnt receive a key. LOL! I…am in that bracket XD

I hope to get in next time! My girlfriend is literally crying because she didn’t get in, she was a huge RO fan.

btw i’m reading this forum since the begenning, but i just made an account for the key, be sure we are plenty like this :stuck_out_tongue:

No keys for me, enjoy the game guys!

Got a key, see you guys in-game when they open!

Dang, didn’t get a key in this first wave. It’s so agonizing waiting for access and constantly being on the watch for more key opportunities. Oh well, we do it to ourselves.

39% is better than 38% lol
