Homework Help: Binomial Distribution - Assumptions

  1. Nov 10, 2011 #1

    An airline knows from past experience that the probability of a person booking a seat and then not turning up is 0.04. A small plane has 50 seats and 55 bookings are made.

    a) A binomial distribution is used to model this situation. What assumption must be made? Comment on how reasonable this assumption must be made

    I really don't know how to answer this, due to the fact my book does not give me much information on Binomial Distribution, just several examples. The only restriction I know of is that there must be Yes and No experiments. In that case, the assumption here would be that no passenger does not book and show up...

    Can anyone give me any tips?

    The binomial distribution is about repeated trials. But look again in your text. You will find an adjective modifying the word trials.
