At a Croissant Factory, Sometimes the Croissants Come Out Too

Short Answer

At a croissant factory, sometimes the croissants come out too dark. After a dark croissant is produced, out of the next 9 croissants, exactly 1 is too dark. After each normal croissant (that is, a croissant with beautiful golden color), out of the next 14 croissants, exactly 12 of them are normal. Find the long run fraction of normal croissants produced.
