Math Question: I have a magical bag that holds an infinite amount of marbles. I have an infinite amount of red marbles and infinite amount of blue marbles in the bag. What is the probability of picking a red marble from the bag?

    If you want these infinte amounts of marbles to be equal, then yes, 50%. But that's something that was not mentioned in the question. Without that piece of information, it's undefined as Neoquest said.

    Then again I could be wrong, I have no idea what I'm talking about.

    When infinity refers to sideways 8, and both of them are the same, then the chance is always 50% and doesnt change with the removal of any number of marbles, even if they are all the same color.

    BUt yes, there are different infinities, but without implying a different infinity we should assume they are equal, and if equal, 50%
