can someone please help me on this question, i just don't get it:
A green bag contains 8 one penny coins and 5 tw pence coins
A yellow bag contains 9 one penny coins and 6 two pence coins
A coin is selected at random from the green bag and placed in the yellow bag
A second coin is then selected at random from the yellow bag and placed in the green bag.
Calculate the probability that the sum of the money in each bag is unchanged after the two transfers?
