this problem is related to measure theory , it is problem 43 on page 123 in Real analysis 4th edition ( Halsey Royden )
if u could please help me to solve it (i , ii ,iii) in steps so I can understand it ,,
I sent it before bt the soln was incomplete and was not clear ...

thank u
Note : I need it as soon as possible
