An airline tracks data on its flight arrivals. Over the past six months, 65 flights on one route arrived early, 273 arrived on time, 218 were late, and 44 were cancelled. What is the probability that a flight is early

0.108

Step-by-step explanation:

Given that:

Number of flights reached early = 65

Number of flights reached on time = 273

Number of flights reached late = 218

Number of flights canceled = 44

To find:

The probability that a flight is early.

Solution:

First of all, let us have a look at the formula for probability of an event E.

Formula for probability of an event E can be observed as:

Here, Event E is that the flight is early.

Number of favorable cases is equal to the number of a flights which reached early i.e. 65

Total number of cases is the total number of flights.

i.e. 65 + 273 + 218 + 44 = 600

So, the required probability is:
