7 Every week the Barbados Tourist Board interviews six randomly chosen vacationers on the islandabout their experience. In general, each vacationer’s comments can be classified as mainly positive ormainly negative. The responses are then published in the Visitor newspaper. Suppose that only 5% of allvisitors to Barbados are dissatisfied with their visit. It is desired to determine the probability that morethan one visitor of the six interviewed will express negative comments? Which of the followingprobability models should be used to find this probability?
