Answer:
The probability that a randomly selected American Airlines flight does not arrive on time is 0.197.
Step-by-step explanation:
The probability of the complement of an event <em>E</em> is the probability of it not happening.
That is,

It is provided that the probability of American Airlines flights arriving on time (<em>X</em>) is,
P(X) = 0.803
Then the event of American Airlines flights not arriving on time is the complement of the event <em>X</em>.
Compute the probability of the complement of event <em>X</em> as follows:

Thus, the probability that a randomly selected American Airlines flight does not arrive on time is 0.197.
