21237.0 as TDateTime
« on: February 21, 2024, 07:54:26 am »
Since the above TDateTime value is today exactly many moons ago (66) I treated myself on a little teaser, after the coffee that is:
Code: Pascal  [Select][+][-]
  1. program BirthdayParadox;
  2. {$mode objfpc}
  3. uses
  4.   sysutils,math;
  5.  
  6. function CalculatePeopleForProbability(p: Double): Integer;
  7. begin
  8.   // Approximate the number of people needed for a given probability
  9.   Result := Ceil(Sqrt(2 * 365 * Ln(1 / (1 - p))));
  10. end;
  11.  
  12. begin
  13.   // Calculate the number of people needed for a 50% probability
  14.   // that two people share the same birthday
  15.   WriteLn('Number of forum members needed for a 50% probability: ', CalculatePeopleForProbability(0.5));
  16.   writeln(DateTimeToStr(21237.0));
  17. end.

But I am sure they don't want the Trumps back...
