moskHola
Seguro que es una chorrada pero esta visto que hoy no me sale es la pregunta 28 del psicotenico nº 11 de la junta de C-M;
José se presenta a un test de oposición sin estudiarse un tema con la mala suerte de que de ese teme le caen 5 pregunta. Si en cada pregunta hay 4 respuestas alternativas. ¿Qué propabilidades tiene de acertar las cinco preguntas respondiendo al azar?
a) 1 entre 256
b) 1 entre 512
c) 1 entre 1024
d) 1 entre 2048
Como correcta da la C,
Un bico y gracias.
murcia27Hola Mosk 😛
Si cada pregunta tiene 4 soluciones posibles… entonces tendrá 1 posibilidad entre 4 de acertar: 1/4, como dice que son 5 preguntas, sería asi:
1/4 x 1/4 x 1/4 x 1/4 x 1/4 = 1 entre 1024
😉 un saludo
manseBuena respuesta. Pero de esta duda que te ha surgido lo importante es aprender la moraleja: intenta ir al examen habiéndote estudiado todos los temas, que nunca se sabe 😕 roll: 😉 😉 😆 😀
moskGracias por ayudarme con la solución del problema y por el consejo.
Un bico
