here's a problem i'm a little confused by:(adsbygoogle = window.adsbygoogle || []).push({});

a limo agency has limos with 4 seats but they book 6 for the same ride because they assume 20% are no-shows. what is the probability that someone will be denied a seat and what is the expected number of empty seats?

i think for the second part the expected number of available seats is 6(.8) but i'm not sure about the probability that someone will be denied a seat. thoughts?
