The average number of customers arriving at a bank branch is
eight per hour. Assume that customer arrivals follow a Poisson
process. The bank opens at 9:00 am in the morning. Answer the
following questions accordingly.
a) What is the probability that the first customer will arrive
after 9:10 am?
b) Suppose that it is now 9:15 and the first customer has
arrived at 9:12 am. What is the probability that the second
customer will arrive after 9:25 am?
c)...

The number of cars arriving at a gas station can be modelled by

station in a 5 -minute interval is _________ b. The probability
that at least one car will arrive to the gas station in a 10 -
minute interval is ______

The number of cars arriving at a
petrol station in a period of t minutes may be assumed to
have a Poisson distribution with mean
720t.
Use this information to
answer questions 31-32.
Find the probability that exactly 12 cars will arrive in one
and half hours.
Find the probability that more than 24 cars will arrive in an
hour.

The number of emails arriving at a server during any one hour
period is known to be a Poisson random variable X with λ = β. The
probability of an email being spam is p.
What is the probability mass function, expected value, and
variance of spam emails in a period of one hour?

The average number of passengers arriving at the Bus Station in
Lancaster on Tuesday between 8:00 and 9:00 is 900.
1.To model this random phenomenon, which probability
distribution is most suitable? Assume that passengers arrive at
random at a constant rate throughout the hour.
2.Using the most suitable probability distribution, consider the
following three statements:
I. There are 15 passengers arriving every minute on average
II. The standard deviation of the number of passengers arriving
in an hour is 30...

Suppose that the mobile company central computer handles 60
million text messages a second. For each text message it handles
assume that there is an (independent) one in twelve million chance
that it will be missed.
What is the expected number of missed test messages in a
second?
What is the variance of the number of missed test messages in a
second?
What are the chances that the central computer misses exactly
four test messages in the next second? (Use...

The number of people arriving for treatment at an emergency room
can be modeled by a Poisson process with a rate parameter of five
per hour. By using Poisson Distributions. Find:
(i) What is the probability that exactly four arrivals occur
during a particular hour?
(ii) What is the probability that at least four people arrive
during a particular hour?
(iii) What is the probability that at least one person arrive
during a particular minute?
(iv) How many people do...

Consider the assumptions of a Poisson process given in class.
Suppose the arrival of cars to a restaurant follows a Poisson
process. Which of the following examples do not violate an
assumption of the Poisson process?
two cars arrive at a restaurant at exactly the same time
the probability of one car arriving between 9:10 and 9:20 is the
same as the probability of one car arriving between 9:25 and
9:35
the probability of one car arriving between 9:04 and...

A grocery store counts the number of customers who arrive during
an hour. The average over a year is 20 customers per hour. Assume
the arrival of customers follows a Poisson distribution. (It
usually does.)
Find the probability that at least one customer arrives in a
particular one minute period. Round your answer to 3
decimals.
Find the probability that at least two customers arrive in a
particular 4 minute period. Round your answer to four decimals.
