A man in the park has a heart attack, two police officers come up to him and say "who is your your next of kin sir, we must inform them if this take a turn for the worse" the man then points to another man in the park and says "brothers, sisters I have none, but that mans father is my fathers son". Then he died.

Who is he pointing to?

i did this one on like page 5 :

 

[TNC9852002]

He's pointing to his son....Classic. Or maybe his nephew?

The man's father's son could be his brother and his brother could be the father or the other man.

can't be a nephew because "brothers sisters i have none"

Nope.

i liked the damn video more.

pointing to himself

He's pointing to his son. 'Nuff said.

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.

 

[Borax]

Grandfather, Father and Son

 

[Majik1387]

Nope. That was my first answer to the guy who asked the riddle

 

[TNC9852002]

I said to myself, what the hell does them driving over a bridge have anything to do with this?

Well, if they drive OVER the bridge and the car crashes, maybe they'll be BLOOD related then if they've been splattered..

[Borax]

Three brothers were out playing golf, had a few drinks and were therefore unable to drive. One of their wives came to pick them up and drive them home. Therefore the son would be her husbands son too... it doesn't say anything about the men driving, just that they were in the car and they just so happen to be going across the bridge

 

[TNC9852002]

One is the father of the other one's son. I'm not sure, Borax. It seems to imply that there are only men in the car, but I dunno.

The first thing that comes to mind is that two of the men are brothers, and one of the brothers is a priest. The third man is a child of the other brother. So one brother is his father, and the other is his 'Father'.


But, the mention of 'putter' as a clue puts me in the mind of golf. Driving over a bridge could imply driving a golf ball over a bridge on a golf course.

 

[Borax]

I have a way out there theory:

They are golf clubs in a golf bag... all woods, the Driver, 3 wood and 5 wood... all blood related because they would be woods, most commonly used to drive different distances on the golf course

Car = Golf Bag
Family = Wood Clubs
Bridge could be on the golf course
And of course one of the clues would relate to this theory



EDIT: I didn't see the post above this until after I posted... I spent forever thinking of this theory only to see someone else has kinda put the same answer

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?

It's been a long long time since I've done statistics. But, looking at it as just another equation, you know the value of several variables. If I understand it correctly (which is highly suspect); P = .95 (final output of equation), N = 25 (population size), M = 20 (number of successes in a lot). I'm not sure what x is, or if my interpretation of what 20 is is right.

But, assuming you have P, N, M, and x, couldn't you substitute the values and solve for n?

I don't know how. Maybe x = 0 (prob of finding one or more)

I'll eventually get something like (?? - n)!/(?? - n)! = ?? I don't know how to divide out those factorials. I thought M would be like 5 or something. I'm not entirely sure. The problem is just worded strangely.

Now that it's piqued my interest, I'll look at it again tomorrow.

 

[TNC9852002]

Heh, it might not make a difference then. I need this information by 7pm tomorrow.

Riddle # 72:

Besides the mathematics, how can the following statement be true?

Eleven plus two = Twelve plus one

Eleven plus two = Twelve plus one

All the letters in the first statement are also in the second

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.
