Answer: 4.4%

Step-by-step explanation:

Probability of drawing blue first is 6 in 15

Assuming you get that one, the second is 5 in 14 (as you've taken a blue one out)

If that's successful you have 5 in 13 chances of pulling another blue

As you want the first AND second AND third to happen, you multiply them…

(6/15)*(5/14)*(4/13) = 0.04395

So as a percentage, to the nearest tenth is 4.4%

¿Cuántos litros de agua se precisa para llenar una piscina inflable de 1/4 de metro cúbico?
8_murik_8 [283]

Answer:

250 litters

Step-by-step explanation:

To solve this question, we first need to know the conversion from cubic meter to liter.

1 cubic meter is equal to 1000 liters.

So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:

1 m3 -> 1000 L

1/4 m3 -> x L

x * 1 = (1/4) * 1000

x = 1000 / 4 = 250 L

So we need 250 liters of water.
