2. Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customer per minute. A Assume that the service times for the drive-up teller follow an exponential probability distribution with a service rate of 36 customers per hour, or 0.6 customer per minute. Use the exponential probability distribution to answer the following questions: i. What is the probability the service time is one minute or less? ii. What is the probability the service time is two minutes or less?

Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 41% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below. ww. a. Find the probability that both generators fail during a power outage. (Round to four decimal places as needed.) b. Find the probability of having a working generator in the event of a power outage. Is that probability high enough for the hospital? Assume the hospital needs both generators to fail less than 1% of the time when needed. (Round to four decimal places as needed.) Is that probability high enough for the hospital? Select the correct answer below and, if necessary, fill in the answer box to complete your choice. OA. Yes, because both generators fail about % of the time they are needed, which is low enough to not impact the health of patients. (Round…
at the bank of california, past data show that 8% of all credit card holders default at some time in their lives. on recent day, this bank issued 12 credit cards to new customers. find the probability that of these 12 customers, eventually a. less than 10 will default b. between 4 to 6 will default
The lifetime of a lightbulb can be modeled with an exponential random variable with an expected lifetime of 1000 days. a. Find the probability that the lightbulb will function for more than 2000 days. b. Find the probability that the lightbulb will function for more than 2000 days, given that it is still functional after 500 days.
An earth-conscious clothing store offers a 15% discount if you bring in a bag full of old clothing to recycle the fabric. The probability that each bag brought in will contain fabric that can actually be recycled is 69%. In a given day, if there are 20 bags of fabric brought in to recycle, calculate the following: Round each answer to 4 decimal places. The probability that at least 9 bags will contain fabric that can be recycled
Suppose a person is looking for a one-year life insurance policy. They decide on a $232994 policy. This policy costs $291 per year. Suppose the probability the person dies in the year is 0.0006. Find the expected value of the policy for the insurance company. Give your answer as a decimal to at least two decimal places.
A family has two cars that are insured, a sports car and a commuting vehicle. The probability that the sports car is in an accident in the next 4 years is 0.014. The probability that the commuting vehicle is in an accident in the next 4 years is 0.004. Assuming that accidents are independent events, compute the probability that at least one of the two cars is in an accident in the next 4 years. Use three decimal place accuracy. (Don't hand writing solution)
On average, TV crash after 17,000 hours of continuous use. Although the time for the TV to crash is random, researchers have found that the duration until the computer crashes follows an exponential probability distribution. a. What is the probability that the TV will fail with a usage time of less than 17,000 hours?b. What is the probability that the TV will crash with a usage time of more than 17,000 hours?c. What is the probability that no TV will fail after more than 17,000 hours of use?d. What do you think about the results of points b and c above! What is the difference?
There is a 0.9984 probability that a randomly selected 28-year-old male lives through the year. A life insurance company charges $168 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit. Complete parts (a) through (c) below.
Given that the switch board of a consultant's office receives on the average 0.6 call per minute, find the probability that (a) In a given minute there will be at least one call. (b) In a 4-minute interval, there will be at least 3 calls.
The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 7.67.6% daily failure rate. Complete parts (a) through (d) below. a. What is the probability that the student's alarm clock will not work on the morning of an important final exam? (Round to three decimal places as needed.) b. If the student has two such alarm clocks, what is the probability that they both fail on the morning of an important final exam? (Round to five decimal places as needed.) c. What is the probability of not being awakened if the student uses three independent alarm clocks? (Round to five decimal places as needed.) d. Do the second and third alarm clocks result in greatly improved reliability? A. Yes, because total malfunction would not be impossible, but it would be unlikely. B. No, because total malfunction would still not be unlikely. C. No, because the…
