Alright, another, hopefully quick, probability question.

Let ( ) and ( ) be inwith -->A and -->B, with P(B)>0 and P( )>0. Show that:A

a) =P(A|B)

b) =P(A|B)

c) =P(A|B)

So, I know that:

= =

= =

= =

= =

My problem really is how to show the limit of , , and is . They seem obvious, but I can't figure out how to show it.
