The fundamental point here is how the question is worded.

If the questions was: IF you get a gold ball, what is the chance the next ball is gold as well? The answer to that is 2/3. It's the question described here: https://en.wikipedia.org/wiki/Bertrand%27s_box_paradox


However, in this question, the first gold ball is a certainty, so the question is: You got a gold ball. What is the chance the next one is a gold ball as well? It's 50%.

It's really the same principle as monty hall you fags
