Answer 1

Answer:

Step-by-step explanation:

Purse A has 9 - 5 paise coins and 1 - 1 rupee coin.

Purse B has 10 - 5 paise coins.

When all 5 paise 9 coins are taken out from the former purse & put into the latter, there are 2 cases,

case (i): from A : 9 - 5 paise coins into B ⟹ purse A has 1 - 1 rupee coin and purse B has 19 - 5 paise coins. The probability of choosing 9 - paise coini10 1

​  

 

case (ii): from A: 8 - 5 paise coins and 1 - 1 rupee coin ⟹ purse A has 1 - 5 paise coin and purse B has 18 - 5 paise coins and 1 - 1 rupee coin. The probability here becomes   10 9

​  

 

Then 9 coins are taken out from the latter & put into the former, so possible cases are:

case (i): from B: 9 - 5 paise coins into A ⟹ purse A has 1 - 1 rupee coin and 9 - 5 paise coins. No change. Here the probability is   10 1

​  

 

case (ii): (a) from B: 8 - 5 paise coins and 1 - 1 rupee coin ⟹ purse A has 9 - 5 paise coins and 1 - 1 rupee coin. No change. Here the probability is    

 18  C  8 ​
