Assuming that dog and cat ownership are independent of each other.In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 202 answered "none," 289 said "one," 365 said "two," 149 said "three," and 43 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05. P(four or more cell phones) = (Round to three decimal places as needed.)In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 217 answered "none," 293 said "one," 369 said "two," 150 said "three," and 73 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05. P(four or more cell phones) =| (Round to three decimal places as needed.) Is it unlikely for a household to have four or more cell phones in use? A. No, because the probability of a respondent with four or more cell phones in use is greater than 0.05. B. Yes, because the probability of a respondent with four or more cell phones in use is greater than 0.05. O C. Yes, because the probability of a respondent with four or…
