You can put this solution on YOUR website! A study of 400 randomly selected American Airlines flights showed that 344 arrived on time. What is the estimated probability of an American Airlines flight arriving late? Is it “unusual” for an American Airlines flight to arrive late?
to find the probability, you would just take 344/400, which simplifies to .86 or 86%.
there's a 14% chance that the airflight will be late, so no, the chance is very low that the flight will be late (Less than 1/5th)
