There are \(n\) balls in the box. There are only black or white balls in the box. The number of white balls is unknown. Assume that that any number of white balls is equiprobable and find a probability to take a white ball from the box at the second time if the first ball that was taken is white. Balls are taken from the box randomly.

aaaah i thought maybe something different. no replacement i assume, and we don't know the first ball right?

what do you want to bet it is one half?

I really don't see how anyone is supposed to come up with a sensible answer to this....

What about http://en.wikipedia.org/wiki/Bayes%27_theorem

How does that help?

Do you know where to use this theorem in general?

I might use Bayesian inference if I had some idea of the percentage of white balls to start with....

Do you know the formula of total probability?

U mean this http://en.wikipedia.org/wiki/Law_of_total_probability

The problem here is that there is insufficient data on which to base any answer to the question.

Any number of white balls is equiprobable, but what about the number of black balls? Is the number of black balls known? Can't find a numerical answer here, but I suspect an algebraic expression at least is possible.
