You select 3 cards without replacement from a deck of 52 cards. Calculate the probability that the first card picked was an ace conditional on the fact that the last two were Jacks. Note that here you need to assume that you are drawing the cards out sequentially .
I think I need to do: P(Ace|Jacks) = (P(Ace ∩ Jacks)) / P(Jacks) But I have hard time to find (P(Ace ∩ Jacks)) and P(Jacks). Can anyone explain this for me? Thanks!
