Answer:

           [tex]\large\boxed{0.24}[/tex]

Explanation:

To make the information easier to handle, write your data using mathematical (probabilities) language:

1. The probability that an international flight leaving the united states is delayed in departing (event d) is .28

  •    P(D) = 0.28

2. The probability that an international flight leaving the united states is a transpacific flight (event p) is .55.

  •    P(P) = 0.55

3. The probability that an international flight leaving the u.s. is a transpacific and is delayed in departing is .13.

  •    P(P∩D) = 0.13

4. What is the probability that an international flight leaving the United States is delayed given that the flight is a transpacific flight?

   P(D/P) = ?

To solve use conditional probability:

  •    Conditional probability formula: P (A/B) = P (A ∩ B) / P(B)

Substituting the data for this problem:

  • P (D/P) = P (D ∩ P) / P (P) = 0.13/0.55 = 0.24
