    Well, how can you express the fact that an event will always occur as a mathematical statement?

    What formula do you know from probability that tells you when 2 events are independent?

    P(anb)=P(a)P(b)

    OK, that's what you want to prove.

    Do you know another formula for P(a n b) involving conditional probability (one that doesn't assume independence)?
