Example 9 Three cards are drawn successively, without replacement from a pack of
52 well shuffled cards What is the probability that first two cards are kings and the
third card drawn is an ace Solution Let K denote the event that the card drawn is king and A be the event that
the card drawn is an ace Clearly, we have to find P (KKA)
Now
P(K) = 4
52
Also, P (K|K) is the probability of second king with the condition that one king has
already been drawn
