Hi Danaj,

What is the strategy to adopt in this kind of question ?

I had answer A but when I read your explanation it makes sense. Do we have to look for a general answer ?

It's the probability to have a white or black marble.
And then, 1/4 is the probability to have the second marble with the same color, and so on.

Thanks in advance.
