If A and B are independent, prove that $\bar A$, $\bar B$ are independent.

Could someone help me start this. It's due tomorrow. I managed to prove that $\bar A [/tex] is independent with [itex] B$ and that $\bar B$ is independent with $A$, but I can't get the last one (the question I put above). Just a little nudge would be good. I've been going in circles trying stuff, from De Morgans law, to every identity I can think of.

Thanks

What are you using as the definition that A and B are independent?
