The sample space is 22 words and out of it, 14 words are known to have meanings for the student. In the problem, we use 10 C8 + 10 C9 + 10 C10 to associate at least 8 words. The complete formula is (10 C8 * (14/22)^8 * (8/22)^2 + 10 C9 (14/22)^9 * (8/22)^1 + 10 C 10 (14/22)^10 * (8/22)^)0) that is equal to 0.233

First you have Define the area of the total shape. Next you'd have to find the area of the unshaded shapes. then you would multiply in that area by floor because there for unshaded boxes. finally you subtract each box from the total area to get an answer of 3x - 4
