In general, if any two events A and B we find that Pr(B|A)=Pr(B), or equivantly,

Pr(AnB)=Pr(A)Pr(B),

then the events A and B are independent.

but i thought that when A and B are independent then Pr(AnB)=0?

what is my teacher trying to say, have i misunderstood something?

(btw n represents intersection)
