In general, the probability of getting exactly k successes in n trials is given by the probability mass function: There are about a 2.4% chance that more than 225 passengers will show up. You can solve the other parts of the question using the same method. For further help with binomial distributions check out: http://mathcentral.uregina.ca/QQ/database/QQ.09.05/belinda1.html
