If the number of calls received per hour by a telephone answering service is a Poisson random variable with parameter A 6, what is the probability of waiting more than 15 minutes between any two succ...
1) The number of calls received at a certain information desk has a Poisson Distribution with an average of 6 calls per hour. (15 points) (a) Find the probability that there is at exactly one call during a 15 minute period. (You cannot use tables here - show all work) (b) Find the probability that at least 6 calls are received during a 30 minute period. (you may use tables here) ******************************** 2) Note that for the above problem, the...
The number of phone calls arriving at a switchboard can be represented by a Poisson random variable. The average number of phone calls per hour is 1.7. (a) Find the probability of getting a total of at least 3 phone calls in the next hour. (b) Find the probability of getting a total of at least 3 phone calls in the next two hours. (c) Find the probability that it is more than 30 minutes until the next call arrives....
The number of requests for assistance received by a towing service is a Poisson process with rate ? = 4 per hour. a) If the operators take a 30 min break for lunch, what is the probability that they do not miss any calls for assistance? b) Assuming they work 10 total hours on a particular day. What is the probability that assist less than 30 people (consider and approximation to help you solve this part)? c) Calculate the average...
A Poisson variable is the number of occurrences of a discrete random variable every hour. Is the probability of no occurrences in any hour equal to the probability that time between two occurrences is greater than one hour? Why or why not?
The number of messages sent to a computer website is a Poisson random variable with a mean of 5 messages per hour. a. What is the probability that 5 messages are received in 1 hours? b. What is the probability that fewer than 2 messages are received in 0.5 hour? c. Let Y be the random variable defined as the time between messages arriving to the computer bulletin board. What is the distribution of Y? What is the mean of...
