Question

Airline passengers arrive randomly and independently at the passenger screening facility at a major international airport. The mean arrival rate is 10 passengers per minute.

- What is the probability of no arrivals in a 1-minute period? If
required, round your answer to six decimal places.

- What is the probability of 3 or fewer arrivals in a 1-minute
period? If required, round your answer to six decimal places.

- What is the probability of no arrivals in a 18-second period?
If required, round your answer to four decimal places.

- What is the probability of at least 1 arrival in a 18-second period? If required, round your answer to four decimal places.

Answer #1

Exercise 5.49
(Algorithmic)}
Airline passengers arrive randomly and independently at the
passenger-screening facility at a major international airport. The
mean arrival rate is 11 passengers per minute.
Compute the probability of
no arrivals in a one-minute period (to 6 decimals).
Compute the probability
that three or fewer passengers arrive in a one-minute period (to 4
decimals).
Compute the probability of
no arrivals in a 15-second period (to 4 decimals).
Compute the probability of
at least one arrival in a 15-second...

POISSON
Airline passengers arrive randomly and independently at
the passenger check-in counter. The average arrival rate is 10
passengers per minute.
a. Calculate the probability that no passenger will arrive
within one minute.
μ = 10 in 1 minute
x = 0 in 1 minute
b. Find the probability that three or fewer passengers will
arrive within one minute.
μ = 10 in 1 minute
x ≤ 3 in 1 minute >>> P (x = 0) +...

Problem 11-18 (Algorithmic)
All airplane passengers at the Lake City Regional Airport must
pass through a security screening area before proceeding to the
boarding area. The airport has three screening stations available,
and the facility manager must decide how many to have open at any
particular time. The service rate for processing passengers at each
screening station is 4.5 passengers per minute. On Monday morning
the arrival rate is 7.2 passengers per minute. Assume that
processing times at each screening...

(8) At Reagan National Airport, there is 1 TSA line/security
scanner open to check passengers for Terminal A. The passengers
have exponentially distributed arrival and departure times. On
average, 2 passengers arrive into the system every minute and it
takes the scanner 25 seconds to process a passenger. What is
the:
i) Average number of
passengers in the queue
ii) Average waiting time in
the queue
iii) Average waiting time in
the system
iv) The probability that 4 or more...

Bus goers come randomly and independently at a checkpoint at a
average rate of 13 passengers per minute. What is the probability
of 8 or fewer arrivals in a one-minute period?

There is a 61 percent chance that an airline passenger will
check bags. In the next 16 passengers that check in for their
flight at Denver International Airport.
(a) Find the probability that all will check bags.
(Round your answer to 4 decimal places.)
P(X = 16)
(b) Find the probability that fewer than 9 will
check bags. (Round your answer to 4 decimal
places.)
P(X < 9)
(c) Find the probability that at least 9...

At an urgent care facility, patients arrive at an average rate
of one patient every five minutes. Assume that the duration between
arrivals is exponentially distributed. (Round your answers to four
decimal places.)
a. Find the probability that the time between two successive visits
to the urgent care facility is less than four minutes.
b. Find the probability that the time between two successive
visits to the urgent care facility is more than 16 minutes.
c. If 10 minutes have...

At a major International Airport, 0.35 of the flights arrive
on time. A sample of 10 flights is studied. What is the probability
that more than 3 of them arrived on time?
Write only a number as your answer. Round to 2 decimal places
(for example 0.24). Do not write as a percentage.
