You are physically contextualizing the problem. It's not about walls or carpets or if you can just move your hand.
It doesn't matter if you can't really realistically move your hand towards a ball because you can't see it.
That again is you playing with the physical loopholes.
There's no magic radar.
It's about a set of distinct objects distributed in distincts subgroups.

You don't know the content of the subgroups.

" [...] probability that the next ball you take from a box [...]?"
"next ball you take from a box"
from A box.

You pick a random, distinct object, inside a random, distinct subgroup.

The point of the boxes is simply to distribute the balls in separate subgroups.
This is just a normal conditional probability problem.
