A tetrahedeon is a four sided object .each side or face is an equilateral rriangle . the number 1,2,3&4 are used to number the different faces. A trial consist of rolling the retrahedron and reading the number that face down then p(4) is____
4 faces total
1 face has a 4 on it
so, p(4) = 1/4
this is just like rolling a regular number cube, but with only 4 faces instead of 6.
