Number of plain can be any number between 0 and 15, exclusive. The same goes for the glazed. They need to total 15 though. Something more
specific relating to one type can determine a specific number of each type.
It can range from 1 plain for .216667, and 14 glazed for .316667 each, to 14 plain at .303333 each, and 1 glazed for .4033333.
I believe this problem doesn't make much sense.
