Explanation
A total of 20 sides, 3 points have three sides, so the probability is 3/20, which is 0.15.
Use the following information to answer questions 47-49.
A regular icosahedron is a solid that has 20 congruent faces, each of which is an equilateral triangle. Each vertex is shared by 5 faces, and each edge is shared by 2 faces.
A specialty die used in a certain board game is in the shape of a regular icosahedron with a certain number of dots on each of the 20 faces. In the image below, 10 faces of the die arc visible.
The table below lists the total number of faces on this die that have the given number of dots.
49. When the specialty die is rolled, only I face will land on top. Each of its faces has the same probability of landing on top. Which of the following values is closest to the probability that the face that lands on top will have 3 dots?
