Answer: it is 1/6
You can solve by saying, 1 out of 6 in each tray is red, so my fraction should be 1/6.
It doesn't matter the amount of trays because the pattern is always the same.
But if you want to check it out you can do it in this way.
You know there is 1 red color per tray, if there are 20 then you'd have 20 of them, in each tray there are 6 colors so the total is 120.
Now you solve it if there are 20 red colors out of 120 them the answer is 20/120, thus you get 1/6
