Do married couples choose similar or differentpersonality types in their mates? The following data give anindication. Similarities andDifferences in a Random Sample of 375 MarriedCouples Number of SimilarPreferences    Number of MarriedCouples Allfour                                    34 Three                                     131 Two                                       124 One                                       71 None                                       15 Suppose that a married couple isselected at random. (a)Use the data to estimate theprobability that the couple will have 0,1,2,3, or 4 personalitypreferences in common. (b)Do the probabilities add upto 1? Why should they? What is the sample space in thisproblem? Please show work Personality Types: IsabelBriggs Myers was a pioneer in the study of personality types.
