Can anyone help me with this proof? I'm completely lost.
Assume A and B are two events such that P(A and B) = P(A) P(B). Consider a third event C. Is it necessarily the case that P(A and B  C) = P(A  C) P(B  C)? If so, prove it. If not, give examples of A, B, and C such that one would reasonably expect that P(A and B) = P(A) P(B) but P(A and B  C) P(A  C) P(B  C).
