Everyone knows me.
Once it was rumored a man drank his fill of me, much to his regret.
Others prefer me in small doses for small ills.
Some describe me as the sky, the land, an age, a tongue, fire, bird, fish, flower.
I am captive, I am free.
Worshiped and lost, loved and eschewed, pure and corrupt, black and white.
I am found in the deepest well, and on the highest mountain.
I am animal, vegetable, mineral.

What am I?

love
life
mankind
mothernature

 

[wiegeabo]

love

None of those.

I got a riddle told to me 3 weeks ago but no answer yet sadly. It's been on my mind for weeks. Here is te way it was told to me.

Three men are in a car. They drive over a bridge. They are blood related. How are they related if one is the father of the other one's son?

Here are the clues I was given (In spoilers for the die hard ridder people)

Spoiler

No religion, sperm donation, gayness, sex changes, or any Jerry Springer things are part of the answer. The son is not in the car. And the word 'Putter' is a clue to the answer. It's also apparently an old Asian riddle, I think Japanese.

No answer yet?

Not those. I'll give a hint in that most of the clues should be taken literally. Something fits in with those description.

Well, since you know what n is, why not try solving for x? Once you know what x is, you can see where it comes from in the problem, and you'll know why all the variables are what they are.

Hmmm...I could try that. I did try going backwards by using n, trying to see if I could get P = .95, but that didn't work. It would come out as something else.

This isn't quite a brain teaser, but it's a homework problem of mine that I'm struggling with.

I believe it's a hypergeometric probability distribution problem.

"A purchaser will reject a lot size N = 25 with the decision rule of finding one or more nonconforming components in a sample of size n, and wants the lot to be rejected with probability at least 0.95 if the lost contains five or more nonconforming components.

What is n?"


I know the answer is n = 11 and I've spent almost two hours on trying to figure out how to prove it.

Any takers?

Gold? or Oil?

 

[Carcharodon]

Between water, gold and oil, oil makes the most sense...not sure if that's the answer though. I'd considered it.

If so, however, oil would be an ambiguous term: nobody I know drinks petroleum for their ills, though some drink cod liver oil.
