B because there is only one negative and -63 divided by 7 equals -9. If it were -7 divided by 63 that would give you an answer in decimal form.

en una caja hay 8 canicas cinco rojas y tres verdes y la Bola que se retira no se reemplaza determina Cuál es la probabilidad de
postnew [5]

Answer: 0.107

Step-by-step explanation:

En una caja tenemos 8 canicas.

5 son rojas

3 son verdes.

Se retira una canica, y no se remplaza.

Quiero calcular la probabilidad de sacar dos canicas verdes.

La probabilidad de sacar una canica verde en el primer intento, es igual al cociente entre el numero de canicas verdes y el numero total de canicas.

p1 = 3/8  

Ahora, en el segundo intento, en la caja voy a tener 2 canicas verdes (por que ya saque una) y 7 canicas en total. Entonces la probabilidad va a ser:

p2 = 2/7.

Y la probabilidad conjunta (es decir, la probabilidad de sacar las dos canicas de color verde) va a ser igual al producto de las probabilidades individuales.

P = p1*p2 = (3/8)*(2/7) = 0.107
