Shоw Wоrk: Fоr pаrt а, pleаse show the fraction you used to answer the probability. Then, type the decimal you find into the box below. **Note: I need to see you using the calculator on your computer to find the answer In a survey of cellphone consumers, respondents were asked how many cell phones were in use by the household. Results among the respondents were as follows: 10 answered "none" 200 said "one" 360 said "two" 150 said "three" 85 respondents said four or more a) A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. (Round to three decimal places as needed.) P(four or more) = [1] (Round to three decimal places as needed.) b) Is it unlikely or likely 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. Type your answer in the box in lower case - likely or unlikely. [2]
