==Gambler's ruin==
If q is the  risk of losing one  throw in a win-or-lose winner-takes-all game in which an amount c is repeatedly staked, and k is the amount with which the gambler starts, then the risk, r,  of losing it all is given by:
:::: r    =    n''(q/p)''<sup>(k/c)</sup>
where p  =  (1-q), and q  ≠  1/2

Gambler's ruin

If q is the risk of losing one throw in a win-or-lose winner-takes-all game in which an amount c is repeatedly staked, and k is the amount with which the gambler starts, then the risk, r, of losing it all is given by:

r = n(q/p)(k/c)

where p = (1-q), and q ≠ 1/2
