Homework Help: Probability Theory

  1. Feb 8, 2007 #1
    If A and B are independent, prove that [itex] \bar A [/itex], [itex] \bar B [/itex] are independent.

    Could someone help me start this. It's due tomorrow. I managed to prove that [itex] \bar A [/tex] is independent with [itex] B [/itex] and that [itex] \bar B [/itex] is independent with [itex] A [/itex], 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?

    For A and B being independent,
    P[AB]=P[A]P

    The professor posted the solution. Later :)
