3√24= 3√2^2*6 = 3*2√6 = 6√6

2√384= 2√8^2*6 = 2*8√6 = 16√6

√96= √4^2*6 = 4√6

6√6 -16√6- 4√6 = -14√6

Final answer: -14√6

En la final de un concurso escolar de

Sati [7]

Usando la distribución hipergeométrica, la probabilidad de que los alumnos del colegio A obtengan los dos premios (no hay empates), es: 0.2 = 20%.

<h3>¿Qué es la fórmula de distribución hipergeométrica?</h3>

La fórmula es:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Los parámetros son:

x es el número de éxitos.

N es el tamaño de la población.

n es el tamaño de la muestra.

k es el número total de resultados deseados.

Los valores de los parámetros son:

N = 6, k = 3, n = 2.

La probabilidad de que los alumnos del colegio A obtengan los dos premios (no hay empates), es P(X = 2), por eso:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,6,2,3) = \frac{C_{3,2}C_{3,0}}{C_{6,2}} = 0.2$
