Hey, can anyone help me with this problem? Its a grade 12 problem.
There are only five perfectly symmertrical holyhedrons :The terrahedren (2 faces), the cube (4 faces), the octahedren (8 faces), the dodecahedren (10 faces), the icosahedren (20 faces). Calculate the expected value for dies made in each of these shapes.
The expected value is the predicted average of all possible outcomes of a probabilty experiment.
