# Thread: binomial distribution

1. ## binomial distribution

A researcher is investigating pedestrian traffic congestion at the entries to a public space. One of the statistics recorded is the number of pedestrians using each entry (passing in or out) in successive 10-minute periods during a working day. If X is the number of pedestrians recorded in each 10-minute interval, would X follow a binomial distribution? Justify your answer.

i recon it would, but i'd be guessing

2. It can be Poison as well if the number of people entering that place over time is very small.

3. what do you mean by Poison?

Why do you think that it would?

The question you need to ask yourself is: Is the experiment a Bernoulli trial if the answer is yes then it can be modeled with a binomial distribution.

5. thank you for that )))

It is a discrete probability distribution Poisson distribution - Wikipedia, the free encyclopedia
