Start with a bag containing 5 white beans. Randomly draw one at a time employing the following rule:
If the bean is white, color it black and put it back in the bag;
If the bean is black, keep it out.
What is the probability that at some point there will be a single white bean in the bag?
Generalize to start with N beans.
Does the probability converge, and if so, to what value?

You seem to be reading 'a single white bean' as
One white and any number of black (which is guaranteed to happen at some point)
Rather than the intended
Just a single bean and it is white (which is not)
