Chance distribution on runewords

[Sagitarii]

Where can I find what the chance is to roll certain modvalues? For example, I want to know what the chance is to roll 35% fcr on a Spirit (I've got 33 now, 2% short of my 125 breakpoint :rolleyes:) but I'm not sure if I should be re-rolling.
And it is nice to know if I should be investing HR's in certain runewords, or buying them with known modvalues.

The chances are distributed evenly, i.e. each percentage or amount is as likely as the other.

There are 11 possible fcr values on Spirit, so the chance for a particular amount (e.g. 35% :azn:) is 1 in 11.

Does that mean if you reroll the spirit 11 times in a row that your bound to get 35% fcr?

No, because each roll is separate and has no bearing on future or pass rolls. If that were true then if you toss a coin twice you would definately get 1 heads and 1 tails, because each have a 50/50 chance, but that's not the case. If you roll a spirit 10 times without getting a 35% FCR, then on your 11th try you still have 1/11 chance of getting 35%.

First attempt you have: 1/11 chance of getting 35fcr
second attempt: 1/11 chance
third attempt: 1/11 chance
fourth: 1/11

etc

The chance of rolling a 35% spirit after n tries is (1- (10/11)^n)*100%. After 11 tries you would have a 65% chance.

It makes sense now. Thanx for clearin it up ya'll ^^
