>So a weighted coin and a fair coin therefore have the exact same odds. Right?
No, because weight, and this applies to a regular coin as well, is a physical influence, but in the case of a coin flip you would also have to take into consideration the strength at which you flip the coin, the air resistance, how high do you flip it, how fast of a spin do you give it, none of this applies to you picking a box, there is no physical law or mechanism which forces you to choose one box over the other
>You had a 1/3 chance of picking any of the three boxes
But there are only two boxes, the question states you pull out a gold ball, that only leaves you with two choices, the only outcomes are that the second ball is gold or it is not, ergo a 50/50 probability
