Repeated Trials Probability?

this is a tough question. i asked many people so far but they keep giving me different answers. so i'm hoping that yahoo answers will give me a general consensus which is similar to mine.

a tetrahedral (four sided) dice has the numbers 1-4 on its faces. it is rolled six times. find the probability of the following outcomes.

A) it lands on the face numbered 4 every time.

B) it never lands of the face numbered 4.

C) it lands on the 4 face at least once.

D) At least once it lands on a face other than the 4 face.

i know it looks like i'm trying to get you to do my homework, but i'm actually teaching myself maths, if i had a teacher to ask it would save me a lot of time.
