prove occurrences are independently of each other

I have problems with this task, I couldnt join the lecture and now i dont get it (Headbang) so every help would be appreciated (Clapping)

Throw two times a fair dice. Prove that these occurrences are pairwise independently of each other but not independently of each other.

A = "number of the first cast of dice is even"

B = "number of the second cast of dice is odd"

C= " both numbers are either even or odd"

Thanks
