Benito es un catador de vinos que escoge y compra las bebidas para un restaurante famoso, y quien compra vinos finos en cargamentos de 15 botellas. Su método para revisar si cada vino está en buen estado toma algo de tiempo, por lo tanto, él sólo prueba 5 botellas de cada cargamento. Si Benito recibe un cargamento que contiene 2 botellas de vino en mal estado, ¿cuál es la probabilidad de que encuentre al menos una de ellas mientras las prueba?
