20/20 + 20/20 != 40/40

(1/1)

Mo:
So for some reason people are under the impression that a 20/20 wand + 20/20 focus gives you 40/40.

I knew there was something wrong with this assumption because if I flip a coin twice the odds of me getting heads once is not 100%.

50% + 50% != 100%

You can't simply add probabilities like this.  Since my stats class was so long ago I couldn't come up with the answer off the top of my head.  So I looked it up and it seems like this is the answer:

p(Either A or B or both happens) = p(A happens) + p(B happens) - p(Both A and B happen)

and p(Both A and B happening) = p(a) x p(b)

works out to 20% + 20% - 4% = 36%.  I actually thought it would be lower.

So the final word on 20/20 wand + 20/20 focus give you a 36/36 !

Meclar:
That's what most of the innate properties of weapons are in GW is just an increased chance for more damage HCT or HSR
Please don't take the joy of a 40/40 away from me!
It's just what's it's called.  A tank isn't actually a tank with tracks and a cannon.  >.<
