Winners of the N900 PUSH Showcase tickets.

Like all great things, they must come to an end. As such, at 10am PST, this morning – our N900 Push competition came to a close. We had some really awesome answers, some really round about, and of course the obligatory – really bad ones. For those that are just on the EDGE of your seat waiting for the final concluding answer to stop the arguing and fighting – to settle this whole dispute. The answer, and the winners are…After the break.

Just to recap, the question -

You’re working with any one of the team winners in the PUSH N900 competition. Your team needs two like resistors in order to complete the project on time.

Luckily your work drawer is overflowing with resistors, and you know that there are only 4 different values since you pulled them yourself from old junk.

You close your eyes and reach in. What is the minimum amount of resistors you have to pull out to ensure 2 of the same value?

The Correct answer is 5 resistors. [Talin Salway][Sari Ibrahim], [James R. Smoot], [Jody Halyk], and [Thomas Remmert] all sent in the correct answer, were picked by us, and gracefully pass their tickets to another winner. In the end [Robrecht Noens] was the only one to respond within our 24 hour limit claiming tickets. Congratulations, and hope you have fun at the N900 PUSH Showcase [Robrecht]!

For all those that sadly, did not win. You can still keep up on the party, [Matt] let us know…

We’ll be updating our @PUSHN900 Twitter account regularly using the #PUSHN900 hashtag to help follow what you guys are saying.
We’ll be uploading video using Qik.com/PUSHN900
Keep checking the PUSH N900 Facebook page for updates as well.

And finally an explanation: The entire riddle (as a lot of readers repeated to us in the entries) is based on the Pigeonhole Principle. In the worst case scenario, you reach in and pull out 4 different values. Thus, you must pull out 5 to ensure at least 2 match.

    Can someone explain to me what stops me randomly pulling out five similar resistors?

  2. HarmonyThruChaos says:

    Nothing will stop you from pulling out 5 similar resistors, but that doesn’t really relate to the question. It’s simply asking how many will you need to pull so that you are Guaranteed to have at least one pair of matching resistors.

  3. Matthew says:

    That’s not the point, bob. You may of course find two similar resistors in the first two pulls or even five similar resistors in the first five pulls, but it cannot be guaranteed that you will have two similar resistors in your hands until you’ve pulled out five. You may end up drawing {A, B, C, D} as your first four resistors, but there’s no way to draw a fifth resistor without having two that are similar.

    > ensure at least 2 match

    bob bob bob bob!

  5. ClutchDude says:

    Or, if you’re me, you pull out the wrong values every time, necessitating the entire drawer to be pulled out and emptied on your desk because “you just know that value resistor you need is in there somewhere.”

    I’m guessing a lot of people got this one. :D

  7. YAY I WON!!! Looks like those thousands of dollars at MS&T finally paid off, wait, what, I learned all that in highschool? Then why am I going to college???!!!

    Whats this about the tickets though? I couldn’t of gone to a different country anyway, but I never got a “you won” e-mail…??? Damn spam folder!!! Congrats Robrecht Noens, I hope you can make it to the show!!! Congrats everyone else too!!!

    this question was like those TV adverts where you can win a car if you guess the right answer out of three, and text the TV guys your A/B/C.

  9. wdfowty says:

    wow. that looks so simple now.

  10. Spork says:

    My drawers are very well organized. It would take exactly two for me to get a similar value resistor.

    Why is that not a valid answer? If I pulled them all out myself, you don’t think I’d organize them?

    High School? …I heard this riddle in like 3rd grade, but it was socks instead of resistors.

  12. charliex says:

    Now I’m just have to wait for the day when i come across someone with a drawer full of resistors with only 4 values (and that they’re ones needed) so i can use this useful tip.

    Thanks science!

  13. Spork says:

    @charliex
    I realize the post was meant to be comical, but.. is it going to be a blind person that you come across? Because otherwise he can just look and grab two of the same.
