Solution

Para resolver esta pregunta, debemos encontrar la probabilidad de dos eventos independientes: obtener una cara en la moneda y un 3 en el dado.

  1. Probabilidad de obtener una cara en la moneda:

    • Una moneda tiene dos caras: cara y cruz.
    • La probabilidad de obtener una cara es 12 \frac{1}{2} .
  2. Probabilidad de obtener un 3 en el dado:

    • Un dado tiene seis caras, numeradas del 1 al 6.
    • La probabilidad de obtener un 3 es 16 \frac{1}{6} .
  3. Probabilidad de ambos eventos ocurriendo juntos:

    • Como los eventos son independientes, multiplicamos las probabilidades individuales.
    • 12×16=112 \frac{1}{2} \times \frac{1}{6} = \frac{1}{12} .

Por lo tanto, la probabilidad de obtener una cara en la moneda y un 3 en el dado es 112 \frac{1}{12} .

La respuesta correcta es: b. 112 \frac{1}{12}
