comment Profit estimation with a dice: 10 dollars for 6, -1 dollar for anything else
I don't disagree, but I also think that OP is new to the subject and probably haven't been taught the mathematical vocabulary to express himself in the proper way. From OP's statements I think it's inferred that we're talking about expectation, or 'probabilistic common sense' as he put it. His lack of formalism does not make him wrong.

Naa, he's kinda right. Every 6 throws he'll get $5, on average. He's just stating it in a convoluted way.
