A person has two vessels (A & B) that contain white and blue balls. In the Vessel 'A' there are 8 white and 8 blue balls and, in the Vessel, 'B' there are 5 white and 6 blue balls. One ball is drawn out from any of these two vessels. What is the probability that the ball drawn is blue?
Total balls in A vessel = 16, Total balls in b vessel = 11 A vessel = 1/2 {(8C1/16C1)} = 1/4 B vessel = 1/2 {(6C1/11C1)} = 3/11 Total Probability = 1/4 + 3/11 = 23/44
