Question

Consider the Edmonton International Airport on a busy summer day. Which of the following arrival patterns would be LEAST likely to follow a Poisson arrival process:

taxi cabs arriving at the taxi stand at the Edmonton International Airport, hoping to find a waiting passenger

travellers requiring the use of emergency medical services within the main terminal at the Edmonton International Airport

passengers arriving at the taxi stand at the Edmonton International Airport hoping to find a waiting cab

flights landing at the Edmonton International Airport

taxi cabs arriving at the taxi stand at the Edmonton International Airport, hoping to find a waiting passenger

travellers requiring the use of emergency medical services within the main terminal at the Edmonton International Airport

passengers arriving at the taxi stand at the Edmonton International Airport hoping to find a waiting cab

flights landing at the Edmonton International Airport

Explanation / Answer

Option c.

Passengers arrive at the taxi stand in clusters because once a flight arrives there will be a rush of passengers in the taxi stand. So number of passengers arriving after the flight arrives will not satisfy the condition of a poisson process that events occur at a fixed rate 'lamda' and probability of one occurnece in a fixed time interval t is lamda*t and that there is negligible probability of more than one occurence in an t time. Because its unlikely that only one passenger will come in time t after a flight arrives.
