Hi;

In order for me to check the answers I will need the positions of the poles too. Remember the distance between the poles count too!

Hi phrontister;

Hi anonimnystefy;

I guess you are saying that the biggest pole is 484 ft high the ant travels 2 * 484 +1 =969 ft and then the next pole is at least 485 ft. away so we have 969 + 485 = 1454 and you can arbitrarily fit 6 small poles in the remaining 114 ft.

Hi bobbym

Why would it need to be 485 ft away?

But, yeah, that's the idea...

Hi anonimnystefy;

The next pole always needs to be further away than the height of the pole before it.

Yeah, but it could be an yoctometer further away than the height of the pole.

That is true, but to simplify calculations I used an integer.

Well, you didn't state that the distance must be an integer, so you cannot assume it to be true...

I did not say it was. But it could be true! Anyway it was for illustration only.

Yes, I would think it is true.

Okay then. Thanks for the problem. I just don't understand why you made it so that it has so many solutions (knowing mine and phro's aren't the only ones...)

Bafflers are not that tough of a problem. Like in the real world, you never know about a problem until you solve it.

There is a collection of 12 balls of same color and weight except one ball of different weight. By using only a weighing balance ( with two pans) without weights,find the odd ball from the lot.Also determine if the odd ball is heavier or lighter than the rest.Only three weighments are allowed.

Ok... But we still need more expectation problems...

Do you need help with that or are you posing it as a problem?

In either case,

is a solution.

I know everything about expectation, or at least I did. I can give you plenty of them if you want to learn it. Start a new thread.

But be aware that they are generally very tough.

Hmmmm, well that sounds like pretty tough talk but if I remember correctly there is still that 1000 die thrown problem...

So? It doesn't mean that I didn't gain anything from working on that problem...

I know... But before you took a trip in to expectation land it would have been more productive to have learned the techniques of solving that one.

Though it is being set up using gf's it is best solved by other means.

Do you remember the Colonels major criticism of bobbym, well pappym said another one? Between the two you could see how he was doomed to failure before he even started.
