76

Friends, the contest is over! The winning number was 3, picked by R. Schumacher. Thanks everybody for joining the contest!

'ello, ladies and gentlemen, boys and girls, ducks and mallards, children of all ages! It is time for organizing another amazing community lottery, our beloved duck giveaway 2016! Quack!

The prize

The prize will be a lovely duck! Not a real one, I am afraid (note to self: organize another lottery with real ducks in the future), it will be a hand puppet duck:

Quack!

Lovely, isn't it?

Again, why a duck? Why not a lion?

As I mentioned in the thread linked here, I always like to provide examples with ducks when I write answers. To my surprise, the theme got a very positive feedback from the community and it spread to everybody. Of course, a lion would be better, but hey, it's free! And it's a duck! :)

Why a hand puppet?

This will be our second lottery offering a duck puppet and I still have absolutely no idea. But since I got this duck again, I thought it would be a good idea to start a contest! :)

Rules

Rules from last lottery still apply:

  • To win the duck you must guess a number in the range 1-200. The first person who guesses the right number gets the duck.

  • Contestants may submit 2 valid guesses.

  • Please post your guess as an answer to this meta question, not as a comment.

  • Contestants must have been a member of TeX.sx before 1 March, 2016.

Two additional mentions:

  • If two or more people choose the same number, only the oldest entry will be considered. The other guesses will be automatically disqualified.

  • If you win the contest, I will need your real name and address for shipping and customs purposes (you can contact me through email, so only I will have privileged access). If you seek anonymity, we advise you to not enter this contest.

Please don't forget to edit the punch card with your numbers.

% the announcement
The winner is \winner, with \winningnumber! Congratulations!

\end{document}

I will run this code with all the contestants, post a video of it and announce the winner. The "accepted answer" in this thread will reflect the winning number.

The date

Hopefully, I will get the code running on July 1, 2016 (Friday), and announce the winner. There will be enough time for guessing the numbers!

Good luck! And by the way, welcome to TeX.sx, the friendliest and most awesome community in the whole StackExchange network! They give us hats, right? We give ducks! Quack! :)

129 and 134.

Just for fun: I did some research and found out that if two numbers are distributed evenly on [0;1], the expected value of their absolute difference should be 1/3 (e.g. not too far apart). Of course no prior research can leverage guessing a random number... But I love birds so much! Keeping decorative chickens and quails at many points in time, and also consuming foie gras with great pleasure! Does everyone remember the hunter (played by Graham Chapman) in Monty Python’s flying circus? “I love animals. That’s why I kill ’em!” So any kind of duck will do: a puppet, a live animal or a nice package of sliced duck breast... Yummi!

Rick Dees and his Disco Duck

Last but not least... Rick Dees and his Disco Duck (A.K.A. if only wearing those bell-bottom jeans in 2016 paid off for me!).

As in the previous context was already taken, I'll go for 022 this time. Second: 171

    Grazie mille, Claudio! – Paulo Cereda May 29 '16 at 20:27

Since duck shall be the answer, and since even random seems to be duck-dependant in this case, I choose:

  • 39 because DUCK = 4+21+3+11
  • 196 because DUCK = 4*21*3*11 = 2772 and 2*7*7*2=196
  • Thank you for joining the contest! – Paulo Cereda May 30 '16 at 10:24
  • And 1*9*6 = 54 and 5*4 = 20 and 2*0 = 0. – Karlo Jan 29 at 10:32

16 and 109 (the present year and my reputation modulo 200, corrected from 108 as in comments).

Duck, duck. Quack, quack!

  • Quack! Thank you for joining the contest! – Paulo Cereda May 29 '16 at 10:59
  • @PauloCereda :-). And, because Alan Munn observed that 108 is already taken, may I change it to a first free number above it? I would simply write that it is 109, but 1st free above 108 is a safer formulation. – Przemysław Scherwentke May 29 '16 at 20:39
  • ooh safer formulations :) – Paulo Cereda Jun 2 '16 at 11:22

41 and 43 for they are the smallest available twin primes.

  • Thank you for joining the contest! – Paulo Cereda Jun 1 '16 at 10:41

Others have used random number generators to come up with their guesses. But ultimately, random number generators still depend on physical processes. They have stochasticism, but I can do better. By selecting numbers myself, using my own imagination and creativity to do so, I am tapping into something that is neither deterministic nor random, but something yet more unpredictable - the free will of the human spirit! Controllable, yet not controlled by the rules of nature!

Um, I'll go with 10 and 100. That sounds good.

  • (I know that 1 and 2 were already selected. I'm not a very active member on this site, so I think a more veteran user deserves the prize. I just thought it would be fun to join in with a silly post :D) – Kevin Jun 2 '16 at 18:27
  • Hi Kevin! C'mon buddy, pick two valid numbers! Everyone in this community is important! Think of the possibility of winning a duck! Please, reconsider. :) – Paulo Cereda Jun 2 '16 at 18:31
  • If you insist :) I'll go with 10 and 100, two suitably uninspired numbers. – Kevin Jun 2 '16 at 18:38
  • Thank you very much! – Paulo Cereda Jun 2 '16 at 18:42
3

93 (because 91 - the only number less than 100 that looks like a prime but isn't - is taken)

105 (because it's 3*5*7 and what 7 subway tokens cost in NY years ago)

Let's take 20 and 46 since they are the only left numbers in the duck-duck-goose game sequence http://oeis.org/A182459 :)

1 (bronze badge) and 179 (my reputation). That's me today.

121 and 141 because I like palindromes and there's something nice about an even number being flanked by odd numbers.

  • Thanks for joining the contest! – Paulo Cereda Jun 7 '16 at 12:16

I take 051 because my current IP ends with that number and 127 because it is 0x1111111. :)
