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%
