Procs with normal weapon attack?

[ibugsy]

So if a skills says it has x % to proc on normal weapon attack and you have 2 skills that do so, do you have a chance to have both proc at the same time or does one proc and you lose the other.
If you lose the other is there any reason to take more than one proc on normal skill?
Example inquisitor 20% to proc with ranged weapon. is there a point in taking fire and cold?
Also if you are using a demo as your secondary class would fire strike “stack” with the proc or be replaced by it?
If you are duel wielding pistols does each pistol get a chance to proc ?

Thank you guys I’m sure you’ve seen a thread like this but I can not find the info.
