A gambler is holding 3 coins.

heads. What is the likelihood
that the other side is tails?

This is a statistical type problem
and not a trick. If a
hen and a half can lay an egg
and a half in a day and a
half, how many eggs can six
hens lay in seven days?
Answer is 28 eggs
The solution using logic is
1.5 hens = 1.5 eggs in
1.5 days
1.5 hens = 1.0 eggs in
1.0 days
6.0 hens = 4.0 eggs in
1.0 days
6.0 hens = 28.0 eggs in 7.0
days

give some to three of his neighbors.
He gave Sam half of the eggs
he'd gathered, plus half of
one egg. Next, he visited
Betty and gave her half of the
eggs he had left, plus half
of an egg.
Finally, the farmer gave John
half of the remaining eggs,
plush half of an egg.
Then he returned home with exactly
one egg.
The farmer never had to actually
cut an egg in halfhe
just "rounded up" the number
by half an egg in each

PROB.  Two Trains And A Fly (S539c)
From: Science Jokes on 7/18/01
Source: http://www.xs4all.nl/~jcdverha/scijokes/
(Also see 'Two Bikes And A Pigeon' in MATH4SUPP)
John von Neumann (19031957)
[Hungarian/US mathematician
and scientist]
The following problem can be
solved either the easy way
or the hard way.
Two trains 200 miles apart are
moving toward each other;
each one is going at a speed
of 50 miles per hour. A fly
starting on the front of one
of them flies back and forth
between them at a rate of 75
miles per hour. It does this
until the trains collide and
crush the fly to death. What
is the total distance the fly
has flown?
The fly actually hits each train
an infinite number of
times before it gets crushed,
and one could solve the
problem the hard way with pencil
and paper by summing an
infinite series of distances.
The easy way is as follows:
Since the trains are 200 miles
apart and each train is
going 50 miles an hour, it takes
2 hours for the trains to
collide. Therefore the
fly was flying for two hours.
Since the fly was flying at
a rate of 75 miles per hour,
the fly must have flown 150
miles. That's all there is
to it.
When this problem was posed to
John von Neumann, he
immediately replied, "150 miles."
"It is very strange," said the
poser, "but nearly everyone
tries to sum the infinite series."
"What do you mean, strange?"
asked Von Neumann. "That's
how I did it!"

PROB.  Five Houses (S161, DU)
From: scott_pryor on 2/28/00
Facts:
1. There are 5
houses in 5 different colors.
2. In each house
lives a person with a different
nationality.
3. These 5 owners
drink a certain beverage, smoke
a certain brand of cigar and keep a certain pet.
4. No owners have
the same pet, smoke the same brand
of cigar or drink the same drink.
Hints:
1. The Brit lives
in a red house.
2. The Swede keeps
dogs as pets.
3. The Dane drinks
tea.
4. The green house
is on the left of the white house.
5. The green house
owner drinks coffee.
6. The person who
smokes Pall Mall rears birds.
7. The owner of
the yellow house smokes Dunhill.
8. The man living
in the house right in the centre
drinks milk.
9. The Norwegian
lives in the first house.
10. The man who smokes
Blend lives next to
the one who keeps cats.
11. The man who keeps
horses lives next to
the man who smokes Dunhill.
12. The owner who smokes
Blue Master drinks beer.
13. The German smokes
Prince.
14. The Norwegian lives
next to the blue house.
15. The man who smokes
Blend has a neighbour who
drinks water.
The question is ... WHO OWNS THE FISH?
If you still are working on it,
or don't have a clue
how to start, draw five large
squares, left to right,
representing the houses.
You know the first (on the
left) has the Norwegian, you
know he is next to the
blue house, so that has to be
the second house, and
you know the middle house has
the milk drinker in it.
The rest has to be deducted
from that. I went for
determining the color of each
house early on. There
may be another way to solve
it, of course.
It's the German who has the fish:
1. Yellow, Norwegian, Dunhill, water, cats
2. Blue, Dane, Blend, tea, horses
3. Red, Brit, Pallmall, milk, birds
4. Green, German, Prince, coffee, fish
5. White, Swede, Bluemaster, beer, dogs

Questions:
1. A murderer is condemned to
death. He has to choose between
three rooms.
The first is full of raging fires, the
second is full
of assassins with loaded guns, and the
third is full of
lions that haven't eaten in 3 years.
Which room is safest
for him?
(Also see 'Explain

2. A woman shoots her husband.Then
she holds him under water
for over 5 minutes.
Finally, she hangs him. But five
minutes later they
both go out together and enjoy a
wonderful dinner
together. How can this be?
3. A magician was boasting one
day at how long he could
hold his breath
under water. His record was 6 minutes.
A kid that was
listening said, "that's nothing, I can
stay under water
for 10 minutes using no types of
equipment or air
pockets!" The magician told the kid if
he could do that,
he'd give him $10,000. The kid did it
and won the money.
Can you figure out how?
4. There are two plastic jugs

6. Can you name three consecutive
