Solution

Primero, necesitamos calcular la proporción de visitantes que no compraron ningún disfraz en el día dado.

La información proporcionada es:

  • 151 visitantes no compraron ningún disfraz.
  • 85 visitantes compraron exactamente un disfraz.
  • 23 visitantes compraron más de un disfraz.

El total de visitantes es: 151+85+23=259 151 + 85 + 23 = 259

La proporción de visitantes que no compraron ningún disfraz es: 151259 \frac{151}{259}

Ahora, si Ian espera 100 visitantes la próxima semana, podemos usar esta proporción para estimar cuántos de ellos no comprarán ningún disfraz: 151259×10058.3 \frac{151}{259} \times 100 \approx 58.3

Redondeando al número entero más cercano, esperamos que aproximadamente: 58 58 visitantes no compren ningún disfraz.
