I am interested in studying the number of customers arriving at a bank during lunch hour. What type of distribution this data will follow? ANSWER: The number of arrivals can have discrete values as 0,1,2,...

generally very less number of customers arrive during the lunch hour, but on a particular day due to some emergency there could be huge number of customers visiting the bank, thus we could not guess the maximum number of arrivals during this period, but we could count the number. The distribution considered for arrivals is Poisson distribution.
