I remember seeing a question from a YouTube video about probability, forgot what it was, but the question was something like this:
"Imagine you have a box containing an infinite amount of marbles, with each marble being one of N different colors. If you keep drawing marbles until you have at least one marble of each color, throwing away all the marbles you drew after this and starting over, how many will you draw on average each time?"
My personal intuition is that it's the Nth triangular number, but I'm not sure how I would go around proving that or if this is even correct. 172.112.210.32 ( talk) 17:56, 8 October 2022 (UTC)
