Question
The Census Bureau says that the 10 most common names in the United State are (in order) Smith, Johnson, Williams, Jones, Brown, Davis, Miller, Wilson, Moore, and Taylor. These names account for 5.6% of all U.S. residents. Out of curiosity, you look at the authors of the textbooks for your current courses. There are 12 authors in all. Would you be surprised if none of the names of these authors were among the 10 most common? Give a probability to support your answer and explain the reasoning behind your calculation.Explanation / Answer
the probabilty that one author is not among the 10 most commonis
P1 = (1-0.056)
the probabilty that all 12 author are not among the 10 most common is
P = (1-0.056)12 = 0.50
so I won't be surprised given the probabiltiy is 50%
