Give yourself a minute or two to solve this :(adsbygoogle = window.adsbygoogle || []).push({});

You have 2 boxes and 20 balls, 10 black and 10 white. How would you distribute the balls in the boxes (any number in each box so long as the total is 20) to maximize the odds of picking 2 whites on a random selection of 1 ball from each box ?

i.e: how many blacks and whites in each box ?
