Apothem is the height of a triangel formed by two consecutive vertices with the center. the are of this triangle = 1/2 s 8 = 4s
there area 12 such triangles in the regular 12 side polygon
So area = 12 * 4 s = 48 s
Less than 2 videos = 0 or 1 videos
P(1) = 1 - 0.1 - 0.3 - 0.2 - 0.1 = 0.3
P(0 or 1 video) = 0.1 + 0.3 = 0.4
Answer: 0.4
-0.9 then 0.74. -0.9 then 0.7
5. -9.87 then 9.08
