english: Here's an example: if I were to tell you, let's play a little coin toss game, and I'm going to flip a coin, and if it comes up heads, I'm going to pay you 10 dollars, but you have to pay four dollars for the privilege of playing with me, most of you would say, sure, I'll take that bet. Because you know that the odds of you winning are one half, the gain if you do is 10 dollars, that multiplies to five, and that's more than I'm charging you to play. So, the answer is, yes.
non_english: Uvediem príklad: ak by som vám povedal, zahrajme si hru hlava alebo znak, a budem hádzať mincou, keď padne hlava, dám vám 10 dolárov ale musíte zaplatiť 4 doláre za to, že vôbec budete hrať. Väčšina z vás by povedala, jasné, to beriem. Pretože viete že pravdepodobnosť výhry je jedna polovica, výhra je 10 dolárov, a keď to vynásobíte, dostanete 5, čo je viac ako poplatok za hru. Takže odpoveď znie áno.
