In Gin-Rummy, how likely is that a round ends in a Draw?
I have played Gin often with my family, at least several hundred rounds. I do not recall ever having participated in a game which ended in a draw.

I will note that I have primarily participated in two-player games, logic indicates that games with additional players would have a higher probability of ending in a draw as there would be fewer rounds per player and each additional player results in one card per round that cannot be accessed.
