Answer:

P(D|P)= \frac{0.11}{0.59}=0.186

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:

P(D)= 0.29 , P(P) = 0.59

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

P(D \cap P) =0.11

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:

P(D|P)

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

P(A|B) = \frac{P(A \cap B)}{P(B)}

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

P(D|P)= \frac{P(D \cap P)}{P(P)}

And if we replace the values we got:

P(D|P)= \frac{0.11}{0.59}=0.186

b. P (blue) = 3/9 = <u>1/3</u>

c. P (green) = <u>4/9</u>

d. Green, because out of the three types of gumballs, the green gumballs are more in number, therefore, it is the one you are most likely to get.
