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
So cola bottle is a cylinder.
Surface area of a cylinder:
1/8 d = how much each niece receives
Each niece receives(x) amount of money.1/8 of the money)
If you multiply this amount by 8 it will be the money Helen divides up to her 8 nieces 1/8dx8=8/8(the whole amount is 8/8)
Unit of the Surface Area with dimension in cm would be: cm²
Hope this helps!
For Urn 1,
total number of balls = 8 (green balls) + 12 (red balls) = 20 balls
The probability of picking a red ball from Urn 1 is equal to 12/20 or 6/10 or 3/5.
For Urn 2,
total number of balls = 5 (green balls) + 8 (red balls) = 13 balls
The probability of picking a red ball is 8/13.
The probability of picking both red balls from the two urns is the product of the two probabilities which gives us the answer which is equal to 24/65. The answer is letter B.
