Solve the problem. Round your answer, as needed. Opinion-polling organizations contact their respondents by sampling random telephone numbers. Assume that interviewers can now reach about 71% of U.S. households, while the percentage of those contacted who agree to cooperate with the survey is 31%. Each household, of course, is independent of the others. What is the probability of failing to contact a household or of contacting the household but not getting them to agree to the interview?
