Cashless Society. 40% of consumers believe that cash will be obsolete in the next 20 years (based on a survey by J.P. Morgan Chase). In each of Exercises 15-20, assume that 8 consumers are randomly selected. Find the indicated probability. E 15. Find the probability that exactly 6 of the selected consumers believe that cash will be obso- lete in the next 20 years. 16. Find the probability that at least 6 of the selected consumers believe that cash will be obso- lete in the next 20 years. 17. Find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years. 2 18. Find the probability that no more than 3 of the selected consumers believe that cash will be obsolete in the next 20 years. 19. Find the probability that none of the selected consumers believes that cash will be obsolete in the next 20 years. 20. Find the probability that at least one of the selected consumers believes that cash will be obsolete in the next 20 years. In Exercises 21-24, assume that when human resource managers are randomly selected, 65% of them say that after submitting a résumé, job applicants should follow up within two weeks. 2+21. If 10 human resource managers are randomly selected, find the probability that exactly 6 of them say job applicants should follow up within two weeks. XE22. If 16 human resource managers are randomly selected, find the probability that exactly 12 of them say job applicants should follow up within two weeks. X:23. If 20 human resource managers are randomly selected, find the probability that at least 18 of them say job applicants should follow up within two weeks. XE24. If 14 human resource managers are randomly selected, find the probability that fewer than 3 of them say job applicants should follow up within two weeks. In Exercises 25-28, find the probabilities and answer the questions.
