A bag contain 4 red and 4 black ball.another bag contain 2 red and 6 black ball.One of the two bags is selected at random and a ball is drawn from the bag which is found to be red. Find thye probability that the ball is drawn from the first bag.

A bag contains 4 red and 4 black balls,another bag contains 2 red and 6 black balls.One of the two bags is selected at random and two balls are drawn at random without replacement from the bag and are found to be both red.Find the probability that the balls are drawn from the first bag.

(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 red and 5 black balls. Another bag contains 6 red and 4 black balls. A ball is transferred from first bag to the second bag and then a ball is drawn from the second bag. Find the probability that the ball drawn is red.

(i) Bag I contains 3 red and 4 black balls while another bag II contains 5 red and 6 black balls. One ball is drawn at random from one of the bags and it is found to be red. Find the probability that it was drawn from bag II. (ii) There are two bags I and II. Bag I contains 4 white and 3 red balls and bag II contains 6 white and 5 red 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 from bag II.

Bag I contains 3 red and 4 black balls while another Bag II contains 5 red and 6 black balls.One ball is drawn at random from one of the bags and it is found to be red.Find the probability that it was drawn from Bag II.

Bag l 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 the black. Find the probability it was drawn from bag I.

Bag l 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 the black. Find the probability it was drawn from bag.

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.
