My office has two chairs and I like students to be able to sit down when they come to office hours. I don't mind standing. Suppose that 1% of students in the class I teach attends my office hours. There are 220 students enrolled in my class and they decide to come to office hours independently. I wonder whether I will have to get more chairs during office hours today. i) The number of students who will show up at my office hours can be modeled by a Binomial model. What are the parameters? ii) Could you use a Poisson model to approximate this Binomial model and why? If so, what is its parameter? iii) Using the Poisson model, what is the probability that I will need to get exactly one additional chair? iv) Using the Poisson model, what is the probability that I won't have to get additional chairs? v) Using the Poisson model, what is the probability that I will need to get more than one additional chair?
