maybe I'm too tired and can't think it straight 
Can anyone help out with the third statement?
Thanks in advance!

Hello irisjojojo
The ratio of magnetic cones to magnetic spheres is equal to the percentage of solids that are either heavier than 5 ounces or magnetic.
First, calculate the ratio of magnetic spheres to magnetic cones by sorting the column reflecting magnetism. There is one magnetic sphere and there are two magnetic cones, so this ratio is 1:2. Next, calculate the percentage of solids that are either heavier than 5 ounces or magnetic by sorting first by weight and then by magnetism. There are 3 solids weighing heavier than 5 oz and 4 solids that are magnetic. However, one solid, K04, is both. The formula for "either x or y" is "number of x's + number of y's – number of both x and y.", so the number of solids that are either heavier than 5 oz. or magnetic is 6, which is exactly 1/2 of the solids. Thus, the ratio and the percentage are the same and this statement is true.
