There are three bags `B_(1),B_(2),B_(3),B_(1)` contians 5 red and 5 green balls. `B_(2)` contains 3 red and 5 green balls and `B_3` contains 5 red and 3 green balls, bags `B_(1),B_(2)` and `B_(3)` have probabilities 3/10, 3/10, and 4/10
respectively of bieng chosen. A bag is selected at randon and a ball is randomly chosen from the bag. then which of the following options is/are correct?

There are three bags B_(1), B_(2) and B_(3) . The bag B_(1) contains 4 red and 4 black balls, B_(2) contains 3 red and 4 black balls, B_(3) contains 4 red and 3 black balls. Bags B_(1), B_(2) and B_(3) have probabilities (1)/(6), (1)/(3) and (1)/(2) respectively of being chosen. A bag is selected at random and a ball is chosen at random from the bag. Then probability of getting a red ball is?

Bag A contains 4green and 3red balls and bag B contains 4red and 3green balls. One bag is taken at random and a ball is drawn and noted to be green. The probability that it comes from bag B, is

A bag contains 5 red and 4 green balls and another bag contains 3 red and 7 black balls. If a ball is drawn from each bag. Find the probability that both are of different colours.

A bag contains 3 red and 5 black balls and second bag contains 6 red and 4 black balls.A ball is drawn from each bag.Find the probability that one is red and the other is black.

Bag A contains 4 green and 3 red balls and bag B contains 4 red and 3 green balls.One bag is taken at random and a ball is drawn and noted it is green.The probability that it comes bag B is (A) 2/7 (B) 2/3 (C) 3/7 (D) 1/3

A bag contains 5 red and 3 green balls and a second bag contains 3 red and 5 green balls. One ball is drawn from first bag and two from second bag.Find the probability that of the three balls drawn,two are red and one is green.
