The game of craps is an extremely popular game offered by casino operators. There are some 40 different types of bets that one can place each time the game is played. One of the best bets from a player’s point of view is the Pass Line bet. The probability of winning a Pass Line bet is almost the same as the probability of losing (244495 versus 251495) as we will derive rigorously in this article. Since the “house” has such a small advantage over the players, many players possess the illusion that they have pretty good chance of making a profit or even making a living by playing this game. This article will show that this really is not the case. We will show that the probability of making a profit is almost zero if one plays the game regularly for a relatively long period of time.
