48. 48. MOCK 1,Question 54 Bag A contains 6 white balls and 4 black balls and bag B contains 3 white balls and 2 black balls. A white ball is picked from bag A and put into bag B. Then, three balls are picked from bag B and put into bag A. Find the probability that a ball picked now from bag A is black. 1. 1/4 2. 1/3 3. 7/12 4. 5/12 5. 11/24 @ flkffl’ [Al/ l/(/ ill’
49. 49. Our method Best & the worst case scenario. The probability will lie between them. Best case for the ball to be black: - The 2 balls picked from bag B and put into bag A are both black, with the 3'“ being white. In that case bag A will contain 6 black and 6 white balls and hence the probability of picking a black ball would be 6/12. Worst case for the ball to be black: - All the 3 balls picked from ba B and put into bag A are white. In that case bag A will contain 8 white and 4 black balls and hence the probability of picking a black ball would be 4/12. This eliminates many options like 1,2 & 3. @ (/ llffl’ Ml/ l/(HM
