can somebody help me???

OpenStudy (anonymous):

Which one is it?

OpenStudy (michele_laino):

Hint: the shaded region include the points enclosed by the ellipse. Furthermore the points which belong to our ellipse don't belong to the shaded region.

OpenStudy (anonymous):

So is it the last answer?

OpenStudy (michele_laino):

no, since the last answer says all points outside the ellipse

OpenStudy (anonymous):

Okay. so its the first one?

OpenStudy (michele_laino):

yes! the first one is the correct answer, since it says all the points inside the ellipse, and those points don't belong to our ellipse.
