Customers arriving at a store according to a Poisson process with an average rate of 2.5 per hours. The store opens its door at 9 AM. (a) What is the probability that the first customer arrives at the store before 11 AM? (b) What is the probability that the first two customers arrive at the store before 11 AM? (c) What is the probability that the first three customers arrive at the store before 11 AM?

Step 1
5 customers per hour. This means that the time between arrivals of customers follows an exponential distribution. The parameter λ (lambda) of the exponential distribution is equal to the rate of the Poisson process, which is 2.5 customers per hour. Show more…

The Poisson Probability Distribution
(b) Suppose customers arrive in a store according to a Poisson process of rate λ = 8 customers per hour. The store opens at 8 am. (i) Find the probability of observing at most 2 customers arriving at the store during a 15-minute interval. (5 marks) (ii) Find the probability that 12 customers arrive before 10 am and there is a total of 16 arrivals by 11 am. (7 marks) (iii) Find the probability that the inter-arrival time of customers is less than 1 minute. (6 marks)
