Question: A barber shop has an average of 12 customers between 8.00am and 9.00am every Saturday. Customers arrive according to Poisson distribution. Let X represent the time between arrivals.
- Construct the distribution for the random variable X?
- Find the mean and standard deviation of X.
- What is the probability that the time between consecutive arrivals (customers) will fall between 3 and 6 minutes?
