Solution

Para resolver esta pregunta, sigamos los siguientes pasos:

  1. Identificar los números en un dado: Un dado bien equilibrado tiene seis caras, numeradas del 1 al 6.

  2. 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)
  3. Contar los números primos: Hay 3 números primos (2, 3 y 5).

  4. 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).

    Probabilidad=Nuˊmero de resultados favorablesNuˊmero total de resultados=36=0.50 \text{Probabilidad} = \frac{\text{Número de resultados favorables}}{\text{Número total de resultados}} = \frac{3}{6} = 0.50

Por lo tanto, la respuesta correcta es:

b. 0.50
