You are allowed to move the balls between the boxes so that
There are two boxes, one containing 10 red balls and the
other containing 10 green balls.when you choose a box at
random and a ball at random from the chosen box, the
probability of getting a red ball is maximized. This maximum
probability is

When ever you think your selected box have maximum no of
probability that means p(ball taken) maximum is 1.
but you must first select the box from two boxes this p(box
choosen) is always constant=1/2.
Finally the answer is maximum p(getting a red ball)=1/2
