There are 180 flights from an airport,20 of which are longer then 3 hours . The flight from this airport will be randomly chosen. What is the probability it is longer then 3 hours ? As a fraction

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.

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

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
