An office building has 2 fire detectors. Suppose that 3 out of every 100 fire detectors will fail to go off during a fire. Find the probability that both of these fire detectors will fail to go off during a fire. Assume that these two fire detectors are independent of each other.

In Questions 2-4 suppose there are a total of 15 Carbon Monoxide Detectors in a building and event “Y” is defined as Y={At least 9 of these detectors work}. Further suppose P(each detector work)=0.8, and detectors are independent of each other. Which of the following is the Ybar (complement of Y)? A. Ybar={At least 5 detectors fail} B. Ybar={At least 6 detectors fail} C. Ybar={At most 6 detectors fail} D. Ybar={At least 7 detectors fail} E. Ybar={At most 7 detectors...

Every day a company makes 100 phone calls. Each call has a 40% chance of being answered. Calls are answered or not independently of each other. Every time a call is answered a sale is made in the amount X that is a random variable having a normal distribution with μ= 50 and σ= 5. Let Y be the number of answered calls during a day and let W be the total amount of daily sales. Assume that sales amounts...

Suppose that 1 out of every 200 students has Meningitis. Suppose there is a test T for Meningitis. Suppose that this test, like any test, is NOT 100% accurate. In particular, sup- pose that the probability that you test positive GIVEN that you have Meningitis equals .97. Suppose that the probability that you test negative GIVEN that you DO NOT have Mengingitis equals .92. Suppose you pick a random student, and test them for Meningitis using the test T. Consider...

a) A man jumps off the roof of an office building onto a trampoline 30 m below. His speed is 5 m/s when he umps from the roof and his mass (with all of her gear) is 60 kg. How high will he go when he bounces back up from the trampoline? You can assume his speed at the top of his bounce is zero. b) Describe the changes in mechanical energy that take place during his jump. c) A...

Problem 3. (2 points) Consumers in Shelbyville have a choice of one of two fast food restaurants, Krusty's and McDonald's. Both have trouble keeping customers. Of those who last went to Krusty's, 56% will go to McDonald's next time, and of those who last went to McDonald's, 82% will go to Krusty's next time. (a) Find the transition matrix describing this situation (assume that state 1 is "Krusty's" and state 2 is "McDonald's"). (b) A customer goes out for fast...
