A restaurant opens from 6:30am to 10:30pm every day. A study
shows that the number of
customers arriving at the station per hour can be modelled by a
Poisson distribution with a
mean of 20 customers per hour.
(a) Find the standard deviation of the number of customer arrivals
over a two-hour
period.
(b) Find the probability that the arrival time between two
successive customers is less
than 10 minutes.
(c) Find the probability that the second customer will arrive the
station before 7:15am
tomorrow.
