You have a choice to play one of three games for money:
Choice A: there are 6 dice in a box with which you are to roll a six
Choice B: there are 12 dice in a box with whch you are to roll two sixes
Choice C: there are 18 dice in a box with whch you are to roll three sixes
Which of these options has the best odds? Why? Note, that for some reason I know the answer, but my memory of stats has eluded me, so I have not written out the (simple) proof yet.
