A bag contains 2 Red, 3 Green and 2 Blue balls. Two balls are drawn randomly from the bag What is the probability that none of then is red ?

A bag contains 6 balls .if 4 are drawn at a time and all of then are found to be red, then probability that exactly 5 of the balls in the bag are red is

There are 3 bags which are known to contain 2 white and 3 black, 4 white and 1 black, and 3 white and 7 black ball, respectively. A ball is drawn at random from one of the bags and found to the black ball. Then the probability that it was drawn from the bag containing the most black ball is
