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, 203 answered "none," 294 said "one," 364 said "two," 143 said "three," and 139 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? O A. Yes, because the probability of a respondent with four or more cell phones in use is less than or equal to 0.05. O B. Yes, because the probability of a respondent with four or more cell phones in use is greater than 0.05. OC. No, because the probability of a respondent with four or more cell phones in use is greater than 0.05. O D. No, because the probability of a respondent with four or more cell phones in use is less than equal to 0.05.

Question
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, 203 answered "none," 294 said "one,"
364 said "two," 143 said "three," and 139 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) =
%3D
(Round to three decimal places as needed.)
