another bag has 5 pink, 6 yellow and 3 blue balls. A bag is selected at random and a ball drawn out of it, then find the probability that the ball drawn is pink.Solution
The probability of choosing bag = 1/2 So, the required probability = 1/2 (Pink ball from bag 1 + Pink ball from bag 2) => 1/2 [(7/14) + (5/14)] => 12/28 = 3/7
