Answer:

Step-by-step explanation:
For this case we have defined the following events:
D= "An international flight leaving the United States is delayed in departing"
P="An international flight leaving the United States is a transpacific flight "
And we have defined the probabilities:

And for the event: "an international flight leaving the U.S. is a transpacific flight and is delayed in departing"
we know the probability:

We want to find this probability:
What is the probability that an international flight leaving the United States is delayed in departing given that the flight is a transpacific flight
So we want this probability:

And we can use the conditional formula from the Bayes theorem given two events A and B:

And if we use this formula for our case we have:

And if we replace the values we got:

Answer:
It would be 3/4 which is the fractional version of 0.75
additive: 1/4+ 2/3=3/4
