Bag I contains 3 red and 4 and Bag II contains 4 red and 5 . One ball is transferred from Bag I to Bag II and then a ball is drawn from Bag II at random. The ball so drawn is found to be red in colour. Find the probability that the transferred ball is *****.
Let E1, E2 and A be event such that E1 = red ball is transferred from Bag I to Bag II E2 = ***** ball is transferred from Bag I to Bag II A = drawing red ball from Bag II Now
From Baye'* theorem.
