80% of an airline's flights depart on-time and 20% do not. of those that depart on-time, 95% arrive on-time. of those that depart late, 10% arrive on-time. what is the chance of someone taking a flight that will arrive on-time?

0.78

Step-by-step explanation:

given that 80% of an airline's flights depart on-time and 20% do not.

Of those that depart on-time, 95% arrive on-time. Of those that depart late, 10% arrive on-time

Let A be the event that flight departs on time.

Now A and A' are mutually exclusive and exhaustive

Let B be the event the flight arrives on time

Using total probability calculation we have

the chance of someone taking a flight that will arrive on-time

= P(B)

=

(x, y)→(x − 8, y − 7)
