Interaction between dodge and evasion

I still don't understand how evasion and dodge interact with each other.

I know that evasion is entropy based and dodge is pseudo random.

Does dodge increase the evasion chance like this(?):

new chance to evade = 1 - (1- chance to evade) * (1- chance to dodge)

and you get your entropy system with this new chance to evade.

Or is dodge rolled before / after the evasion roll(?):

Let's say you get a few hits your entropy counter is above 100 and you would normally get a hit. You now got a x% chance to dodge this hit.

OR

For every hit you get a x% chance to dodge: If you dodge it, it is not added to the entropy counter; if you don't, it is added.

I am stupid. I just realized that it's completely irrelevant which one is rolled first.

Let's say:
x = chance to evade
y = chance to dodge

chance to avoid attack would be :

if evasion is occurred first:

x+(1-x)*y

if dodge occurred first:

y+(1-y)*x

these two formulae are equivalent:

x+(1-x)*y = x + y - x*y = y+(1-y)*x
