Question

There are 108 flights from an airport, 20 of which are longer than 3 hours.

The flight from this airport will be randomly chosen.

What is the probability it is longer than 3 hours?

Answer 1

Answer:

Let's consider the event to be 'A', then,

$P(A) = \frac{20}{108}$

As there are 20 flights out of 108 that are more than 3 hours.

Thanks.
