can you properly explain why you think it's 50% or 2/3?

There's an equal amount of balls of the same color, it's a 50% probability.
No I can't because I'm retarded
1/2, as soon as you know the ball is green, you can remove on of the boxes (all red) from the equation.
2/3 you have to count both of the green balls in the box.
It's 50/50 because the box you pulled a ball out of either has a second green ball or it doesn't.
Jesus christ anons... If you don't know math, just don't answer. Some of you fucking retards who make a big long case for 50% know fucking nothing of statistics and you know it. It's 2/3 because statistics says so. If you don't know statistics, run the experiment yourself 100 times. The answer will not be 50%.
2/3
Each box has an equal chance of being chosen, but the problem set only includes the results when at least one ball is green.
Half of those results will be two greens in the box.
You are not choosing one of four balls. You're choosing one of two problem sets, and only one of those two can result in two greens being drawn.
This isn't the Monty Hall problem.
2/3
Explanation:
You are starting from a position of having already picked a green ball. There are three green balls which have equal chance at being the one you picked. Two of those green balls will have you picking a green ball on the second grab. One of those green balls will have you picking a red ball on the second grab.
