There are 40 markers in a bag. Of the 10 scented markers, 6 are permanent markers. Half of the unscented markers are erasable.Which two-way table is correct?

For this case we have:
 10 scented markers: Column 1, row 3.
 6 are permanent markers: Column 1, row 1
 Half of the unscented markers are erasable: (1/2) * 30 = 15 Column 2, row 2.
 Therefore, the selected table corresponds to the attached image.
 Answer:
 See attached image.
