In total there are 12 marbles because 6+4+2=12 and it says you pick 2 marbles from the hat so you subtract 12-2 and that gives you 10 and it says the marbles aren't returned so therefore you are left with 10 marbles. Hope this helps .

Answer:

3/11

Step-by-step explanation

We have 12 marbles in total

First, picking white ones probability is 6/12

Then we set aside the white marble we chose and now we have 11 marbles in total

The number of non-white marbles is 6 and the probability of choosing one of them is 6/11

6/12*6/11 = 3/11
