Three bags contain a number of red and white balls are as follow: Bag I:3 red balls; Bag II: 2 red balls and 1 white ball; Bag III: 3 white balls if a white ball is selected, what is the probability that it came from (i) Bag II (ii) Bag III

Three bags contain a number of red and white balls as follows Bag I : 3 red balls, Bag II : 2 red balls and 1 white balls and Bag III : 3 white balls. The probability that bag i will be chosen and a ball is selected from it is i/6 , where i=1,2,3. What is the probability that (i) a red ball will be selected? (ii) a white ball is selected?

A bag contains 5 black balls, 4 white balls and 3 red balls. If a ball is selected random wise the probability that it is black or red ball is

A fair die is rolled. If a face 1 turns up, a ball is drawn from Bag A. If face 2 or 3 turns up a ball is drawn from Bag B. If face 4 or 5 or 6 turns up, a ball is drawn from Bag C. A contain 3 red and 2 white balls, Bag B contains 3 red and 4 white balls and Bag C contains 4 red and 5 white balls. The die is rolled, a Bag is picked up and a ball is drawn. If the drawn ball is red, what is the probability that it is drawn from Bag B?
