Given that a randomly chosen flight arrives on time, what is the probability that it arrives in Philadelphia (PHL)?
olga55 [171]

Using concepts of probability, it is found that there is a 4.7% probability that it arrives in Philadelphia (PHL).

<h3>What is a probability?</h3>
  • A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • Over a large number of trials, a percentage can also represent the probability of  single event.

In this question, researching the problem on the internet, we have that over a large number of flights, of those which arrived on time, 4.7% of them were in Philadelphia, hence:

  • There is a 4.7% probability that it arrives in Philadelphia (PHL).
