Imagine that you have three boxes, one containing two black balls, one containing two white balls, and the third containing one black ball and one white ball.
The boxes were originally labelled for their contents (BB - WW - BW) but someone has inadvertently switched the labels so that now every box is incorrectly labelled.
Without looking inside, you are allowed to take one ball at a time out of any box that you wish, and by this process of sampling, you are to determine the contents of all three boxes.
What is the smallest number of drawings needed to do this?
(In reply to
what do you mean not the answer? by Lucifer)
hey Lucifer, just see the category of this problem, its "LOGIC", so I believe there is always a possibility for such a solution to exist, i mean in just one drawing. Well just think a bit more and even you will come up with the correct answer, which is one for this problem. The only thing you are supposed to do is chose the proper box from which you have to make the drawing. That's it.
