It's still 50%.
ETA: Per OT standards, it's 3.50%

Edit for the downvoters. I could be wrong.
I misread.
I give it 50%

50% chance... at least that's what it would seem.
Thinking about it more though... 66.67% is the correct answer.
You're twice as likely to have initially picked the box with two gold balls if the first pull is a gold ball. So 66.67% of the time, you've picked that box and the other ball is gold. 33.33% of the time, you picked the mixed box and the other ball is silver.
Obviously this holds true if the first pull is silver as well. 2/3 boxes contain identical balls, so 2/3 times the second pull will be the same as the first.

66.7% - you know that the box with two silvers is eliminated, leaving only one possible silver ball out of 3.
ETA: I'm right.... SUCK IT DOWNVOTES

I guess if you pick a gold ball then that rules out the box with 2 silver balls.
So the box was either the one with 2 gold or 1 gold and 1 silver.
So you know you are starting with 3 golds and one silver and you just picked one gold. You have left 3 balls, 2 gold and 1 silver. So you odds of picking a gold ball next are roughly 67%.
I think, anyway.

1:2. It’s not about the balls at that point, it’s about the boxes.

It clearly states the same box.

Unless u return the gold ball then it's 50%

Trick question, baw. This is the OT. We grab’em by the pussy, not the balls.

Exactly. The 67% folks are throwing the third box out of the equation without accounting for it.
