could you plz tell me abt Q 40. My logic is as follows but doesnt quite satisfy.

P(Green)=P(Red)= 0.5  as the balls are placed back each time

is it that we would expect to lose as much money by drawing a red ball, as much we earn by picking a green ball; as the prob of doing the two are the same??

and rs 10-10=0??
