as far as i know cards are auto assigned colours as they are picked up by a player thus each of the events is independent and the chances are exactly the same.
if it is not like this then the chances are minutely greater for a mixed set but you definitely have got the chances wrong. if the events were dependent it would be like this:
let X be number of ters on board and let each of the card colours be their first letter; R,B,G
X/3=R=B=G
if X/3=10
player 1 gets a random card; 1/3
card is R
next card (presuming nobody else gets a card) chances are:
R=9/29
B=10/29
G=10/29
repeat etc....
thing is CC didn't make up the rules for the card values.
if they were changed then people who have played the board game would get really confused.

If it's true that this has been discussed before, then thank God for this thread, because it's been discussed incorrectly before.

Why are people so excited about the fact that something has been discussed before? How is that an impediment to discussing it again? Maybe (and I'm sure this never ever happens) the previous discussion wasn't worth a bucket of warm spit. Even if it has been discussed before, then goody for you. It's your lucky day! You can safely skip this thread and apply the time you saved not reading this thread (which has been discussed before) to the more interesting parts of your life. Instead you take the time to respond saying something has been discussed before. If I were interested in whether something was discussed before I guess I could do a search myself. Call me lazy, but I was just more interested in thinking about what the original poster said, regardless of whether it had been discussed before or not.

Well, it turns out the OP is correct about the odds of getting a polychromatic set versus a monochromatic set.
I believe the branch of mathematics is called cominatorics and was correctly applied by the OP.
If you have 3 cards and each card is of one of three possible colors, then there are 3 * 3 * 3 = 27 different combinations. One of those combinations is the case where all the cards are red. One of those is the case where all the cards are green. One where all the cards are blue. Six of the possible combinations result in a case where the set is formed of one of each color. Eighteen result in three cards that do not form a set.
It is in fact twice as common to get a polychromatic set than a monochromatic set.
Surely you have noticed this happening in your own experience playing the game?
