A bag 'A' contains 2 white and 3 red balls, a bag 'B' contains 4 white and 5 black balls. A bag is selected randomly and a ball is drawn from it . Drawn ball is observed to be white. Find the probability that bag 'B' was selected.
A bag A contains 2 white and 3 red balls another bag B contains 4 white and 5 red balls.A bag is chosen at random and a ball is drawn from it.If the ball drawn is red,what is the probability that the bag B is chosen? [CBSE'04C)
(a) (i) Bag I contains 5 red and 3 black balls, Bag II contains 6 red and 5 black balls. One bag is chosen at random and a ball is drawn which is found to be black. Find the probability that it was drawn from Bag I, (II). (ii) Bag I contains 3 red and 5 white balls and bag II contains 4 red and 6 white balls. One of the bags is selected at random and a ball is drawn from it. The ball is found to be red. Find the probability that ball is drawn from Bag II. (b) Bag I contains 4 black and 6 red balls, bag II contains 7 black and 3 red balls and bag III contains 5 black and 5 red balls. One bag is chosen at random and a ball is drawn from it which is found to be red. Find the probability that it was drawn from bag II.
One bag contains 3 white and 2 black balls, another bag contains 5 white and 3 black balls. If a bag is chosen at random and a ball is drawn from it, what is the chance that it is white?
A bag contains 1 white and 6 red balls,and a second bag contains 4 white and 3 red balls. One of the bags is picked up at random and a ball is randomly drawn from it,and is found a be white in colour.Find the probability that the drawn ball was from the first bag.
A bag A contains 2 white and 3 red balls and a bag B contains 4 white and 5 red and balls. One ball is drawn at random from one of the bags and is found to be red. Find the probability that it was drawn as red.
A bag A contains 2 white and 3 red balls and a bag B contains 4 white and 5red balls. One ball is drawn at random from one of the bags and is found to be red. Find the probability that it was drawn as red.
