There are 2 main reasons why no one has answered your question yet:

1. It's here on the Game Updates page instead of on the Seasonal Dragon page.

2. No one knows for sure yet, there has not been enough time for anyone to get around to do any thorough testing on the matter. It shouldn't be as low as the Rainbow since that's the "rarest of all dragons" but from the limited testing done it does seem to be close in that 2-4% vacinity.
