Question

Given a regular dodecahedron (a twelve-sided solid in which each face is a regular pentagon that is congruent with each of the other faces): If this solid is rolled on a surface, what is the probability that a specifically named face will be in contact with the surface?

Answer 1

Answer:

1/12

Step-by-step explanation:

There are 12 faces. All faces are equally likely to land in contact with the surface. We are interested in 1 of the 12 faces.

probability = 1/12
