The probability that an international flight leaving the us is delayed in departing is .31
the probability that an international flight leaving the us is a transpacific flight is .62
the probability that an international flight leaving the us is a transpacific flight and is delayed in departing is .15
what is the probability that an international flight leaving the us is delayed
given the flight is a transpacific flight
~~~~~~~~~~~~~~~~~~~

Let A be the event that "an international flight leaving the us is delayed in departing".

    P(A) = 0.31  (given).



Let B be the event that "an international flight leaving the us is a transpacific flight".

    P(B) = 0.62  (given).



The event that "an international flight leaving the us is a transpacific flight and is delayed 
in departing"  is the intersection (A and B).  The probability  P(A and B) = 0.15  (given).   



They want you calculate the conditional probability  P(A | B). 



By the definition, this conditional probability is  P(A | B) =  =  = 0.2419  (rounded).    ANSWER

Solved (with the complete mantra attached).
