A national survey found that 46% of adults ages 25-29 had only a cell phone and no landline. Suppose that four 25-29-year-olds are randomly selected. Complete parts a through c below. a) What is the probability that all of these adults have only a cell phone and no landline? (Round to four decimal places as needed.) b) What is the probability that none of these adults have only a cell phone and no landline? (Round to four decimal places as needed.) c) What is the probability that at least one of these adults has only a cell phone and no landline? (Round to four decimal places as needed.)
