Problem number 5# Eleven of the 50 digital recorders (DVRs) in an inventory are known to be defective. What is the probability you randomly select an item that is not defective? The probability is —- (Do not round). problem # 6 Identify the sample space of the probability experiment and determine the number of outcomes in the sample space. Randomly choosing an odd number between 1 and 9, inclusive The sample space is—- (Use a comma to separate answers as needed. Use ascending order.) so there are —- outcomes in the sample space. problem#7. A software company is hiring for two positions: a software development engineer and a sales operations manager. How many ways can these positions be filled if there are 19 people applying for the engineering position and 18 people applying for the managerial position? The position can be filled in —- ways. problem#9. Consider a company that selects employees for random drug tests. The company uses a computer to randomly select employees numbers that range from 1 to 5839. Find the probability of selecting a number less than 1000. Find the probability of selecting a number greater than 1000. The probability of selecting a number less than 1000 is–(Round to three decimal places as needed.) The probability of selecting a number greater than 1000 is—(Round to three decimal places as needed.) problem #10. Consider a company that selects employees for random drug tests. The company uses computer to randomly select employee numbers that range from 1 to 6282. Find the probability of selecting a number less than 1000. Find the probability of selecting a number greater than 1000. The probability of selecting a number less than 1000 is— round to three decimal places as needed. The probability of selecting a number greater than 1000 is— round to three decimal places as needed. problem #11. A probability experiment consists of rolling a eight sided die and spinner shown at the right. The spinner is equally likely to land on each color. Use a tree diagram to find the probability of the given event. Then tell whether the event can be considered unusual. Event: rolling a number less than 3 and the spinner landing on yellow the probability of the event is — ( type an integer or decimal rounded to three decimal places as needed.) Can the event be considered unusual? problem #12. Use the frequency distribution, which shows the responses of a survey of college students when asked, “How often do you wear a seat belt when riding in a car driven by someone else?” Find the following probabilities of responses of college students from the survey chosen at random. Response — Never with the frequency of 117, rarely– frequency 344, sometimes– frequency of 569, most of the time with the frequency of 1372, always with the frequency of 2591, complete the table below for the response and the probability
