A 4-sided die, called a tetrahedral die, is a die in the shape of a tetrahedron, with the numbers 1, 2, 3 and 4 each written on one of the four different sides.
When you toss a tetrahedral die, it lands with one corner up and one side down, so you look at the number that lands down. All sides are equally likely to land down.
If, as part of a game, a loonie is flipped and a tetrahedral die is rolled, how many possible outcomes are in the sample space?
