in explorers of sky what is the chance of a secret bazzar being on a floor?

There is no real probability or chance of an Item appearing In a Dungeon, since it is all chosen by Random everytime you enter a floor. Truely, there is no answer since all items are chosen at random.The Secret Bazaar looks like a Suitcase that gives you helpful options for your character.
