Odds of a trimmed/gold item

Approximately, what are the chances of getting a trimmed or a gold item, say, for a level two clue...?

The rewards are supposed to be random. You can't get rune (t) or (g). You can get addy (t) or (g). I think you get (t) more often than (g). But it's supposed to be random. I'd say out of about 9 level 2 clues I got about 4 or 5 addy rares. Hope this helped.
