Put 3 balls on each side.
If they are equal, weigh the other two balls, one on each side - one must be the heavier ball.
If they are not equal, then weigh two of the balls from the heavier side and remember which was the third on that side. If the two you weigh are the same, then the third one is the heaviest. If the two you weigh are different, well, then you've found the heavier of the two.

Tricky :)

You are allowed to miss on purpose (i.e. shoot at nothing).

Shoot at yourself.

How does shooting yourself maximize your chances of survival?

I don't know. I thought someone else would come up with the answer to that. I just tossed out the idea. :p

well, u have a 33% accuracy rate. so 66% chance u miss and hit another cyborg. while aiming will only get u 33%. thus, shoot yourself! w00t!

That is such a leet strategy. I like it.

Which should in fact be 50%, or everyone around me is too smart, because I have yet to see someone unable to figure it

You are allowed to miss on purpose (i.e. shoot at nothing).
If you shoot at either 2 or 3 your probability of survival is 7/18 or 38.9%, assuming 2 and 3 make optimal choices.

If you shoot at nothing your probability of survival is 5/12 or 41.7%, assuming 2 and 3 make optimal choices.
Close. If you don't shoot, your chances of survival are 100% since the other Cyborgs cannot fire 'till you fire.

Therefore, don't shoot and just die ... or speed up the process by shooting yourself.

Imagine a giant kangaroo, whose tail is attached to a stake in the ground by a giant rubber band. A tiny flea is sitting on the stake.

The giant kangaroo see the flea and is spooked. He jumps and lands a mile away from the stake (to which it is still attached by the giant rubber band). The flea begins pursuit, hopping onto the rubber band, and lands one inch away from the stake. The kangaroo again jumps another mile away from the stake. The flea jumps another inch along the rubber band. This continues indefinately.

Assuming the earth is flat and infinite, does the flea ever catch up with the kangaroo?

Is the rubber band infinitely elastic?

If the rubber band keeps getting a mile longer every time the flea jumps then he'll never catch up.

but as the kangaroo is jumping and stretching the rubber band.....wouldn't the flea also be moving closer even w/o moving? I guess what I'm saying, although he is stationary on the rubber band, the fact that it stretches will cause him to get closer proportionally i geuss to the amount of stretch. i dunno....
