[Pre-BB] MapleStory Formula Compilation

Sounds like a confirmation to me. You were using TT no?

*Tries something*
Damage Range 30~50, probability to 2 hit a monster with 80 HP

Let me try to do this via the way you do it with dice.

21^2 = 441 possibilities.

Chances to do 80 damage+ added together:
30/50
31/50
32/50
...
50/50
=21

31/49
32/49
...
50/49
=20

etc etc

49/31
50/31
=2

50/30
=1

=(21*22)/2
= 231 chances, 231/441 = 52.4% chance to 2 hit.
Fix'd.

If your average damage is 40, you should always have a greater chance to 2 hit than 50%. This is because you count 40 as part of the 2-hit range instead of a divider.
