What is the probability that the time between the arrivals of two customers will be less than 14 seconds? b. What is the probability that the time between the arrivals of two customers will be between 11 and 19 seconds? c. What is the probability that the time between the arrivals of two customers will be greater than 23 seconds? d.

Answer #1

A busy restaurant determined that between 6:30 P.M. and 9:00
P.M. on Friday nights, the arrivals of customers are Poisson
distributed with an average arrival rate of 4.32 per minute.
*(Round your answer to 2 decimal places.) **(Round your answer to 4
decimal places.)
(a) What is the probability that at least 11 minutes will elapse
between arrivals?
(b) What is the probability that at least 4 minutes will elapse
between arrivals?
(c) What is the probability that at least...

The time (in minutes) between arrivals of customers to a post
office is to be modelled by the Exponential distribution with mean
0.38.
Please give your answers to two decimal places. Given that the
time between consecutive customers arriving is greater than ten
seconds, what is the chance that it is greater than fifteen
seconds

The time between arrivals of vehicles at a particular
intersection follows an exponential probability distribution with a
mean of 10 seconds. (a) Sketch this exponential probability
distribution.
(b) What is the probability that the arrival time between
vehicles is 10 seconds or less? (Round your answer to four decimal
places.)
(c) What is the probability that the arrival time between
vehicles is 4 seconds or less? (Round your answer to four decimal
places.)
(d) What is the probability of 30...

7. A store is expecting n deliveries between the hours
of noon and 1 p.m. Suppose the arrival time of each delivery truck
is uniformly distributed on this 1-hour interval and that the times
are independent of one another.
a) What percentage of the time the latest delivery arrives after
12:50?
b) What percentage of the time the first delivery arrives before
12:10?

Arrivals at a bank are Poisson distributed with a mean arrival
rate of two arrivals every five minutes.
a) What is the probability of exactly two arrivals in the next
four minutes?
b) Assuming that the previous arrival came to the bank 10
minutes ago (with no arrivals since then), what is the probability
that the time to next arrival will be greater than 1 minute?

The time between arrivals at a toll booth follows an
exponential distribution with a mean time between arrivals of 2
minutes.
What is the probability that the time between two successive
arrivals will be less than 3 minutes?
What is the probability that the time will be between 3 and 1
minutes?

If the number of arrivals in a cell phone shop follows a Poisson
distribution, with a reason of 10 clients per hour:
What is the probability that in the next half hour, 4 clients
arrive?
What is the probability that in the next two hours, between 18
and 22 clients arrive?
What is the average time between arrivals?
What is the median of the time between arrivals?
What is the probability that the time that transpires for the
next arrival...

Let X be the time between successive arrivals to an intersection
in a rural area. Suppose cars arrive to the intersection via a
Poisson process at a rate of 1 every 5 minutes.
(a) What distribution does X have?
(b) What is the mean time between arrivals?
(c) What is the probability that more than 7 minutes will pass
between arrivals to the intersection?

Let X = the time between two successive arrivals at the drive-up
window of a local bank.
Suppose that X has an exponential distribution with an average
time between arrivals of 4
minutes.
a. A car has just left the window. What is probability that it
will take more than 4 minutes before the next drive-up to the
window?
b. A car has just left the window. What is the probability that
it will take more than 5 minutes before...

A store typically has 5 customers arrive per hour, and arrivals
follow a Poisson distribution. What is the likelihood that a. no
customers will arrive in an hour? b. less than three customers
arrive in an hour? c. five or more customers arrive in an hour?
