Tiffany Chapman · Answer 1

1/9

Step-by-step explanation:

20 out of 180 flights are longer than 3 hours. So as a fraction that would be 20/180. However, this can be simplified to 1/9.

Hanna Mcclain · Answer 2

1/9

Step-by-step explanation:

Number of flight in the airport = 180

Number of flights which are longer than 3 hours = 20

Probability of choosing a flight longer than 3 hours will be number of flights which are longer than three hours divided by the total number of flights in the airport

That's

20/180

Divide both the numerator and denominator by 20

1/9
