Solution
Para resolver esta pregunta, sigamos los siguientes pasos:
-
Identificar los números en un dado: Un dado bien equilibrado tiene seis caras, numeradas del 1 al 6.
-
Identificar los números primos entre 1 y 6: Los números primos son aquellos que solo tienen dos divisores: 1 y ellos mismos. Entre 1 y 6, los números primos son:
- 2 (divisores: 1 y 2)
- 3 (divisores: 1 y 3)
- 5 (divisores: 1 y 5)
-
Contar los números primos: Hay 3 números primos (2, 3 y 5).
-
Calcular la probabilidad: La probabilidad de obtener un número primo al lanzar el dado es el número de resultados favorables (números primos) dividido por el número total de posibles resultados (caras del dado).
Por lo tanto, la respuesta correcta es:
b. 0.50
