D0s Posted June 12, 2014 Report Share Posted June 12, 2014 Diego tiene una bolsa con cuatro bolitas, 2 rojas y 2 negras. Al sacar las bolitas una a una, ¿cuál es la probabilidad que los colores salgan alternados? Respuesta según la pauta: 1/3 Me quede pegado con este ejercicio :c . Ojala me puedan ayudar. De antemano gracias. Saludos Link to comment Share on other sites More sharing options...
