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.
Un ejemplo: si les digo, juguemos a lanzar una moneda, si al lanzar la moneda sale cara, te pago 10 dólares, pero tienes que pagar 4 dólares por el privilegio de jugar conmigo, la mayoría de ustedes dirá, seguro, acepto la apuesta.
