The table below shows the results of a survey in which 146 families were asked if they own a computer and if they will be taking a summer vacation this year. (a) Find the probability that a randomly selected family is not taking a summer vacation this year. The probability is .301 . (Round to the nearest thousandth as needed.) (b) Find the probability that a randomly selected family owns a computer. The probability is .397 . (Round to the nearest thousandth as needed.) (c) Find the probability a randomly selected family is taking a summer vacation this year given that they own a computer. The probability is .810 . (Round to the nearest thousandth as needed.) (d) Find the probability a randomly selected family is taking a summer vacation this year and owns a computer. The probability is [ ]. (Round to the nearest thousandth as needed.)

Solution

(d) P(taking a summer vacation and owns a computer) = 47/146 =0.322
