Answer :
B makes the most sense because its not 1/2 and its not 1/20 and it leaves B or D and 17/30 is more then half so it can not be D.
No choice on the list is reasonably close to the correct answer.
The question is the same as asking "How much of the whole circle has
black polka-dots in it ?"
The sections of the circle aren't labeled, but we can see that the polka-dot
section is a little more than 1/4 of the circle ... maybe 30% of it ... so the
probability is a little more than 1/4 and close to 30%.
The choices are: A). 50%. ... B). 20%. ... C). 5%. ... D). 56.7%.
Choice B). is the closest, but that's only because the others are even
more absurd. It's not saying much for B).
