Can someone do the math for me?

What math? A dupe Gold within the same draw? If we assume you get exactly two Golds in your 10+1, then the chance of getting two Golds first of all is something like this:
There are 55 combinations of two Gold, and nine non-Gold in an 11 draw (position 1 and 2, 1 and 3, 1 and 4 etc, then position 2 and 3, 2 and 4 etc).
The chance of getting two Gold and nine-none Gold is 6.5%^2 x 93.5%^9 x 55.
The chance of your two Golds being a dupe of each other = 1/n where n = number of different Golds. So if there are 30 Gacha golds, it is 1/30. You multiply that by the previous bit.
That is just the odds of getting exactly one pair of dupe Golds in a 10+1 draw, without factoring in getting the Rainbow in your 9 non Gold which gets even more complicated!
