Oh yeah, they had like give no information of the number of balls or anything else whatsoever :/
I still answered C anyway. Wonder they will give marks for any answer or not.
It wasn't wrong i guess. It was without replacement so ignoring any other information , it should become 7 balls when one ball is out and no replaced back in to the bag.
even i wrote the essay in five minutes.
managed to write two three lines.
and i found the rest of the paper to be veryyy long :(
but are you sure about the sixty bit? :/ :(
