Let's calculate the probability of finding someone special. Using a form of Fermi's Paradox (the difference between having limited or no choices to having high amount of choices). Let's calculate your probability using the following data. Multiply the number and all percentages together N (subscript p): Number of people = your target population (number of people in your state). Broward County, FL is 1,953, 251 million. Dade County, FL is 2,717,251 million. Palm Beach County, FL is 1, 497,251 million. Harris County, TX is 4,731,251 million. (example: 1,374,251 x .5 x .44 x .37 x .25 x.10 x.10 = 279 people are potential special people for you) times f (subscript g) = target gender (multiply as a decimal. Example: 0.5 for either sex or 1.0 for both sexes) times f (subscripts) = single people (multiply as a decimal) About 44% of people are single at any given time. f (subscript e) = the number of people you'll run into (multiply as a decimal). Your sample size will be small if you only…
