OK, you don't like that approach, how about this. I'll try to upload a diagram, but in case that doesn't work, maybe you can follow this.

Starting at the left end of the cable, connect wires together in a group of 4, a group of 3, and a group of 2. (Leaving 1 wire unattached to anything.)

Going to the right side, you can use the battery and the bulb (I assume that your "light ball" is actually a light bulb) to test and identify the wires that are in the 4-group, the 3-group, the 2-group and the single one. Label them a - j as I show in the diagram. Now connect b to e, c to h, d to j, and f to i. (a and g are left unconnected.)

Now go back to the left side with the battery and bulb. Label the wires in each group so you will remember which ones they were, disconnect them from each other, and test to find:
- a wire from the group of 4 that makes no circuit with any other wire - that one is a.
- a wire from the group of 4 that makes a circuit with a wire from the group of 3 - those are b and e.
- a wire from the group of 4 that makes a circuit with one from the group of 2 - those are c and h.
- a wire from the group of 4 that makes a circuit with the one that was originally unconnected - those are d and j.
- a wire from the group of 3 that makes a circuit with one from the group of 2 - those are f and i.
- a wire from the group of 3 that makes no circuit - that is g.

next problem

You are the big winner of a television game show. The host says "Grand prize is behind door #1, 2 or 3. pick one." After you make your choice (lets say you pick #1) the host says "You may be right. It's either #1 or #2 but its not number 3. Now I'm going to give you one last chance do you want to stick with door #1 or would you like to pick again?" What should you do?

I just took the time to answer that horribly long balance puzzle, and my post didn't work. I'm not certain I am right, I am tired and can't think anymore. There is more to it than this, but this is all I had in my clipboard and there is no way in hell I'm typing anymore:

I would take 8 of the 12 balls and weigh them with 4 on each side of the balance.

If they were even, then I would know the odd ball was one of the 4 I haven't weighed. If the balance tipped then I would label the balls on the tipped side as l1 l2 l3 and l4. The balls on the other h1 h2 h3 and h4.

I would then take l1, h4, h3 and weigh against h1, h2 and l2. If the balance was even, then I would know the odd ball was either l3 or l4. if the balance tipped to the first side, then i would know the odd ball was either h4, h3 or l2. if the scale tipped to the second side, then I would know the odd ball was either h1, h2 or l2.

If it was l3 or l4 then I would use my last balance to measure l3 again any ball other than l4. If the scale was even then l4 is the odd ball. If the scale dips to l3 then l3 is the odd ball.

It it was h4, h3, or l2 then I would use my last balance with h4 vs h3. If the balance dips to h4 then h4 is the odd ball. If the balance dips to h3 then h3 is the odd ball. if the scale is even then l2 is the odd ball.

If it was h1, h2, or l2, then I would do the same as directly above and find the odd ball.

If my initial weigh was balanced, then I would take 3 of the 4 remaining balls and weigh them against 3 other balls. If the balance stayed level, then I would know the odd ball was the one I didn't weigh. If it did not, then I would know whether the 3 balls were lighter or heavier. I would then take 2 of the 3 remaining balls and weigh them against eachother. If the balance was level then the odd ball is the one I didn't weigh. Otherwise, it is the heavier/lighter one, depending on whether the 3 balls were lighter or heavier.

isn't it cute? BUT IS WRONG!!! :biggrin: :biggrin: remember that u don't know if the ball is lighter or heavyer...

why?
but you had a good start!!

whatever you want....you have a 33% chance to find the prize....you pick #1...and you find that the door #3 is a fake....Your chances increase to 50%....so either you take #2 or you rest on #1 you heave the same chances to win the prise :)

I had one typo, but the fact that I don't know whether it is heavier or lighter was taken into account. This puzzle would be simple if I knew if it was lighter or heavier.

"if the scale tipped to the second side, then I would know the odd ball was either h1, h2 or l2."

should of been:
"if the scale tipped to the second side, then I would know the odd ball was either h1, h2 or l1."


I can connects the dots if you still think I am wrong, but I'm too lazy to do that until then :P

no I don't think that is correct. its close, but not right. What if there are a million doors and after you choose Monty Hall/Bob Barker throws out 999998 of the bad doors and says it's either the one you chose or this one? do you think it is still a 50/50 chance then?

tribdog if there were 1milion doors you would have 1/1000000 chances to win the prise...if we-ll take off a fake one, either you change or you keep your door, you'll have a 1/999999 chances to win the prize...so...the answer is the same...you can do whatever you like...you have the same chances

leto ... let me give you a hint...try to use the 1st weigh...make 2 options: 1.what if it tippes ao a 1st side, and 2.what if it tippes on second side... You'll have to work longer, but you have a lot more chances to find the odd ball :biggrin:

I disagree. By removing the 999998 doors, the chance of the door you didn't pick being the door increases. The door you did pick could not be removed, and is therefore less likely to be the prized door.

There are three possibilities with the first weigh. Either it tips to the left, right or stays level. I accounted for all three of these.

Edit:

I think you are assuming I label them l1-l4 and h1 - h4 because I assume I know this. I only label them as such so that I know later that, if one of them is the odd ball, they have to follow that pattern. A ball that was on the heavy side will never be the lighter odd ball.
