**How do you calculate the prob of scattering 1 inch or less for a BS of 4?**

- Use the same formula I showed you before, but use a BS of 5 instead of 4

- For 2 inches or less use a BS of 6 instead of a 4

**That gives me the probability of 1 inch or less, how do I get the probability of just scattering 1 inch?**

- Calculate the probability of scattering 1 inch or less, then subtract the probability of not scattering at all, to get the probability of just scattering 1 inch.

**Lets go over some examples**

**To calculate the probability of a blast template scattering 2 inches or less with a BS of 4**

- there are 15 ways to roll a 6 (BS of 4+2) or less on 2D6

P = ( 1/3 ) + ( ( 15 / 36 ) * 2/3 ) = .611 = 61% chance of scattering 2 inches or less with a BS of 4

**To calculate the probability of a blast template scattering just 2 inches**

- Subtract the probability of a blast template scattering 1 inch or less from the probability of scattering 2 inches or less

- P = 61% - 52% = 9%

You can check your results against these

BS of 2

scatter of 0 = 35%

scatter of 1 = 4%

scatter of 2 = 5%

BS of 3

scatter of 0 = 39%

scatter of 1 = 5%

scatter of 2 = 8%

BS of 4

scatter of 0 = 44%

scatter of 1 = 8%

scatter of 2 = 9%

*- Hope this helps!*

So if the BS 4 scatter is 8% for one inch, does that stack with the 44% for the scatter of zero? Meaning, that I have a 52% chance of it landing within one inch of target, 53% chance of hitting within two inches, etc?

ReplyDeleteLoyal Guardsman, that is correct. But if you just want to know the chances of the template landing within 1 inch for a BS of 4, then calculate the formula with a BS of 5. That will give you the 52%. You get the 8% by subtracting the formula done with a BS 4 from the formula done with a BS of 5.

ReplyDeleteIs farseer still being worked on and will it be released for use outside of a blackberry (i.e. on a pc)?

ReplyDeleteI stumbled upon this while wondering about the chance for an Imperial Griffon's barrage to hit / not scattering or not scattering more than 2 inches. The Griffon has a special rule that allows you to reroll the scatter dice.
