Defining S t to be the gambler’s wealth after the t -th game, we have S 0 = M, and, for all integer t ≥ 0 (5) S t + 1 = { S t + X t, S t ≥ ν S t, 0 ≤ S t < ν. We define the sequence S t so that if ruin occurs at some time t 0, then S t = S t 0 ∈ { 0, 1, …, ν − 1 } for all t ≥ t 0, or ...

That is, if we have x dollars, the transition probabilities are: p ( x, x + 1) = 1 / 2 = p ( x, x − 1) Now we add a condition that says if we earn N dollars, we stop playing the game.

So the theorem says that E[X τ] = E[X 0]. In other words, the gambler leaves with the same amount of money on average as when he started. (The same result holds if the gambler, instead of ...
