A bag contains 4 Blue, 5 red and 3 green balls. Debolina is asked to pick up three balls at random, one by one without replacement from that bag. If the balls picked up are of same colour then Debolina will get Rs. 7000, if the balls picked up are of different colour, then she will get Rs. 9000, but otherwise she has to pay Rs. 4000. a) Find the expected gain of Debolina if she plays the game. b)...
