There are two boxes, one containing 39 red balls and the other containing 26 green balls. You are allowed to move the balls between the boxes so that when you chose 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?

• keep 1 red ball in the 1st box and move 38 balls in the next
  so req probability= 1/2*1 + 1/2*(38/38+26)
  =51/64
