    a fair gambling game

    You want to invent a gambling game in which a person rolls two (unbiased) dice
    and is paid some money if the sum is 7, but otherwise he loses his money. How
    much should you pay him for winning a 1 bet if you want this to be a fair game,
    that is, to have expected value 0? (solution: 6)

    so far i got the following

    1/6 chance of winning
    so E(x)=0 = (1/6)x+ (5/6)*-1
    X=5

    he has to pay 5, but that is incorrect

    I think I understand it, I calculated the profit the gambler will make not how much he will get paid, he will get an additional 1 euro.
