I am trying to study for my statistic exam and not sure how to solve this question. The question is :
what is the possibility of the following event: an ace is drawn first and a king is drawn second.
Here is what I have done but not sure if its right.
Using the conditional probability formula : $$P(A|B) = P(A \cap B)/P(B).$$
A = ace is drawn ==> 4/52 ==> 1/13 and
B = king is drawn ==> 1/13.
so now I am not sure how to do $$P(B \cap A)$$
could someone direct me from this point on as to what I need to do to solve this?
