Because when the words random, probability, etc. appear you seem to stop there and treat them in their mathematical meaning rather their relationship to the phenomenon they are describing.
I thought I was being a little facetious with the analogy. Unfortunately, it appears that your argument really is as analogised.

Disprove the analogy without disproving your own claim. Unless you hold that the tenet of the analogy really is true, in which case I dont know of a simpler way to show that the involvement of probability to model a result isnt a substitute for the explanation for that result, nor is their any pretence of such.
Curiously enough, every single environmental possibility cannot be expressed on a page of paper. The effect of the environment upon traits is well understood (more commonly called natural selection) and you should be aware of this if you had studied the subject so why did you highlight the word chance in that passage when it was clear what context it was being inferred in? Oh thats right, you could use the word chance to erect that straw-man of yours.
