Speedy Surveys Inc. one afternoon sent five surveyors to carry out a\nstatistical study on matching birth data from a base point In the walking\nstreet of Mapletown.<\/p>\n\n\n\n
The surveyor would ask a random person to give their first name, day\nand month of birth, then check for a match on their list. As soon as a match\nwas found the surveyor would return to the base point with the list.<\/p>\n\n\n\n
After return of the five surveyors with their lists, the data was\ncollected and the process repeated again for a total of ten times.<\/p>\n\n\n\n
The data were then compiled into a complete report for Speedy Surveys\nInc.<\/p>\n\n\n\n
As a special bonus, surveyors who interviewed someone who had the same\nbirth data as themselves were awarded a free pizza meal at the famous Guiseppe\u2019s\nPizza House.<\/p>\n\n\n\n
What would you say was the average number of persons that had to be interviewed\nby a surveyor to get a birth data match?<\/em><\/p>\n\n\n\n What would you say was the probability that at least two of the five\nsurveyors were awarded a free pizza meal?<\/em><\/p>\nShare this:<\/h3>
