Shelony, se sa nèt. Thank you for helping me demonstrate that if we were told with certitude that a person's birthday could be guessed at in 5 questions or less [given one other piece of information, that is the name of the Haitian president the person was born under], then necessarily, that President would have to be President Damiel Fignolé. Any other president, it might have required more than 5 questions (unless you are extremely good at guessing).
Someone on the Forum told me that my thesis was not valid, because the person might have been born under President Lafontant. Ha ha! I take it as a good joke, as Lafontant held the reins of power for only 10 hours and will never be considered a constitutional president in any case. But that was a good joke!
The last thing I want to say, Shelony, is that while I don't know which year, month, or day you were born, I could deduce your exact birth date using 13 yes/no questions or fewer. Isn't math wonderful? [though, I concede, perhaps not as filled with wonders like biology which is your forte. ]
But there is no need to take on this challenge, as that one lasted LONG ENOUGH!
