there are 6 side on a dice. rolling a five is a 1 out of 6 chance and an even number is a 3 out of six chance. multiply them together to get 3 out of 36 simplify to get 1 out of 12
An imaginary line would need to be drawn at any angle to the center of the side opposite the angle to reflect across an axis of symmetry so that a regular pentagon can carry onto itself. Hope this answer helps.
