Combining Two Dice Pools

Combining Two Dice Pools

I am working on a system using a dice pool system and am not sure how to calculate probability.

The system uses two pools of d6: One for Attribute and one for Skill. They are rolled against different set TN (Attribute is TN 6, Skill is TN 5). I have calculated the probability for each pool on its own. But i don't know how to combine them into a chart.

For example Attribute 2 + Skill 2 (2d6, TN 6 + 2d6, TN 5).

How do I combine these or what formula do I use in the program.

Something like:


A := 2d6; \ attribute pool
S := 2d6; \ skill pool
TA := 6; \ attribute target
TS := 5; \ skill target
(count TA <= A) + (count TS <= S)
