Puzzle about 3 boxes with 2 balls inside (black or white) with mixed labels on them We have 3 boxes. In every one there are 2 balls. One of them has 2 black balls, second 2 white balls, third black and white ball. 
On every box is a right plate(label): BB,WW,BW. Unfortunatelly somebody mixed the plates and now only NONE of the boxes has a right plate on it. You can draw only one random ball from selected box to decode what is in all the boxes. Which box would you choose?
My opininon: I have no clue, because:


*

*if I choose box with a plate BB I only know that it is wrong plate if I draw white ball, but I can draw black ball and it still can be BW box.

*if I choose box with a plate BW I will know nothing about righteousness of a plate on it


Easy. Pick from BW box, what ever color you get (let's say W) that box had to hold 2 of, so it WW. You know that the BB box must hold the the BW balls because it can't hold the BB balls. Only thing left is is the WW box and the BB balls.
