Coloured bills are distributed in three bags as shown in the following table: Bag Colour of the ball   Black White Red I 1 2 3 II 2 4 1 III 4 5 3 A bag is selected at random and then two balls are randomly drawn from the selected bag. They happen to be black and red. What is the probability that they came from bag I?
