Two types of customers (Preferred and Regular) call a service center. Preferred customers call with rate 3 per hour, and Regular customers call with rate 5 per hour. The interarrival times of the calls for each customer type are exponentially distributed. If the call center opens at 8:00 AM, what is the probability that the first call (regardless of customers type who calls) is received before 8:15 AM?

Chase is the general manager for a business. One of Chase's tasks is to assign extra projects to his employees. These extra projects are supposed to be assigned following a particular order. The extra projects result in additional pay, so the employees are concerned that the extra projects are assigned following the proper procedure. Errors do happen though. Chase makes an error once every 54 tasks that he assigns. If Chase were to assign 10 tasks, what is the probability that he would make 3 or more mistakes? .000023 (Round your answer to six decimal places.) When Chase was supposed to assign 10 tasks to Kendra, he DID make 3 mistakes. Was Kendra treated fairly? yes or no What conclusions could you make about the three mistakes? Make sure to explain your conclusion thoroughly.
Sarah throws a fair die multiple times, recording the total number of "2"s she throws and then calculating the proportion of "2"s she has thrown so far after each throw. She then constructs a graph to visualize her results. Which of the following statements is FALSE? a. This is an example of the law of large numbers. b. The theoretical probability of getting a 2 is 0.167 for each throw. c. The relative frequency of "2"s thrown changes as Sarah throws the die more. d. The probability distribution for the possible number of outcomes changes as the total number of throws increases.
shift ↑ ctri otop Insurance: An insurance company sells a 1-year term life insurance policy to an 76-year-old woman. The woman pays a premium of $3600. If she dies within 1 year, the company will pay $90,000 to her beneficiary.

Suppose a free throw shooter makes 67 percent of their first attempts. On the second attempt they make 81 percent if they had made their first attempt, but 59 percent if they had miss. What is the probability that they make one of two attempts (one or the other attempt, but not both)?
Dorothy’s pastries are freshly baked and sold at several specialty shops throughout Perth. When they are a day old, they must be sold at reduced prices. Daily demand is distributed as follows: Demand Probability 50 0.25 150 0.50 200 0.25 Each pastry sells for $1.00 and costs $0.60 to make. Each one not sold at the end of the day can be sold the next day for $0.30 as day-old merchandise. How many pastries should be baked each day?
The proprietor of Midland Construction Company has to decide between two projects. He estimates that the first project will yield a profit of $180,000 with a probability of 0.7 or a profit of $130,000 with a probability of 0.3; the second project will yield a profit of $220,000 with a probability of 0.7 or a profit of $80,000 with a probability of 0.3.Find the expected profit for each project. first project $ second project $
A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?
