The Question: Should you choose the second box, or should you stick to your first choice to maximize the expected amount of money?
Read the hint below if you're stuck...
A Hint: If you have $10, and you could double this with a chance of 1/2, or half it with a chance of 1/2, one would expect an average of 1/2 * $20 + 1/2 * $5 = $12.5 (so you would expect to gain $2.5)!...

Let's say that Ty Cobb's seaon batting average is the same as Shoeless Joe Jackson's at the beginning of a late-season double-header. Assume both batters have had hundreds of at bats.
Cobb went 7 for 8 (.875) while Jackson went 9 for 12 (.750). But at the end of the day, Jackson's season average turned out to be higher than Cobb's. How is this possible?

After breakfast that day, they went out back to check on the jar of tea Grandma had put out that morning. It was gone. "There's Buz," Grandpa said, pointing to a boy out in the field walking away from them. Junior followed Buz out into the field.
As Junior got closer, he could see Buz had a jar in his hand. It was empty.
"What are you doing?" Junior asked, trying to sound friendly.
"I'm catching bees for my collection," Buz said, looking around as if searching for a little victim. "I almost got that yellow-jacket," he said, indicating a large black-and-yellow-striped bee several yards out of reach.
"Do you know a lot about bees?" Junior asked.
"Oh, yes. I study them. I just that yellow jacket and I'll have an example of all the kinds you see around here. By the way, my name's Buz. Who are you?"
"I'm Junior, the guy who caught you stealing my grandmother's tea," Junior replied.
Why is Junior so sure Buz stole the tea?

who can drown in the ocean and yet remain dry.
A last vestige of Man that refuses to die.
In mourning I am tossed at your feet to lie;
I begin my Job early, devouring your ankles and thighs.
I Work my way up, eating your legs to your waist.
And though around midday away I am chased,
I return quickly to savor the arm of my taste.
As evening Falls I enter your lungs,
spiraling Down past your mouth and your tongue.
I feast on your body, your soul, and your mind,
but as darkness falls you shall find
that away I will go, a relief for some;
At least until tomorrow morning comes.

Little trotty hetty coat
in a long petticoat
and a red nose
the longer she stands
the shorter she grows.
The land was white
the seed was black
it'll take a good scholar
to riddle me that.
Riddle me! riddle me! What is that:
Over your head and under your hat?
George walked for thirty minutes in the pouring rain without getting a single hair on his head wet. He didn't have a hat or an umbrella and his coat had no hood. How did he do that?
I'm going to count this as my Sunday puzzle/riddle, so we'll be back on schedule on Monday when I post the answer to these four.

From the jingle of my bell,
But exactly who I am is not an easy thing to tell.
Children, they adore me
for they find me jolly,
but I do not see them when the halls are decked with holly.
My job often leaves me frozen,
I am a man that all should know,
But I do not do business in times of sleet or ice or snow.
I travel much on business,
But no reindeer haul me around,
I do all my traveling firmly on the ground.
I love the time of Christmas,
But that's not my vocational season,
And I assure that is because of a sound economic reason.

I think it's a good idea for several reasons. Perhaps you don't have access to the web, say at work? But you still want to expand your brain a little bit by thinking through a riddle. It also lets me know that there are people who are interested in this site (making it worth my while to post everyday). I know there are some 'regulars' who try to answer the question each day, but I think there are more people who get here later in the day and don't want to post after the answer has been given.
BTW, I've implemented this across my blogs, so if you like to read info on Boston Sports, games on the web, etc... please head on over and sign up there as well.
Take some time and sign up. I'd appreciate it.
While I'm at it, if you have another site to recommend for a syndication button, let me know about it. I want to make your experience here as easy and pleasant as possible.

And each, I assure you, will rhyme with the other.
My first you will find is one-fifth of my second,
And truly my whole a long period reckoned.
Yet my first and my second(nay, think not I cozen),
When added together will make but two dozen.
How many am I?

And played all night till break of day.
They played for cash and not for fun,
With a separate score for every one.
When it came time to square accounts,
they all had made quite fair amounts.
Now, not one has lost and all have gained -
Tell me now, this can you explain?

Here is the proof...
|(1) X = Y||Given|
|(2) X2 = XY||Multiply both sides by X|
|(3) X2 - Y2 = XY - Y2||Subtract Y2 from both sides|
|(4) (X+Y)(X-Y) = Y(X-Y)||Factor both sides|
|(5) (X+Y) = Y||Cancel out common factors|
|(6) Y+Y = Y||Substitute in from line (1)|
|(7) 2Y = Y||Collect the Y's|
|(8) 2 = 1||Divide both sides by Y|

Ten weary, footsore travellers,
All in a woeful plight,
Sought shelter at a wayside inn
One dark and stormy night.
'Nine rooms, no more,' the landlord said
'Have I to offer you.
To each of eight a single bed,
But the ninth must serve for two.'
A din arose. The troubled host
Could only scratch his head,
For of those tired men not two
Would occupy one bed.
The puzzled host was soon at ease -
He was a clever man -
And so to please his guests devised
This most ingeneous plan.
In a room marked A two men were placed,
The third was lodged in B,
The fourth to C was then assigned,
The fifth retired to D.
In E the sixth he tucked away,
In F the sventh man.
The eighth and ninth in G and H,
And then to A he ran,
Wherein the host, as I have said,
Had laid two travellers by;
Then taking one - the tenth and last -
He logged him safe in I.
Nine singe rooms - a room for each -
Were made to serve for ten;
And this it is that puzzles me
And many wiser men.

"Gatsby was walking back from a visit down in Branton Hill's manufacturing district on a Saturday night. A busy day's traffic had had its noisy run; and with not many folks in sight, His Honor got along without having to stop to grasp a hand, or talk; for a mayor out of City Hall is a shining mark for any politician. And so, coming to Broadway, a booming bass drum and sounds of singing, told of a small Salvation Army unit carrying on amidst Broadway's night shopping crowds. Gatsby, walking towards that group, saw a young girl, back toward him, just finishing a long, soulful oration ... "
The above passage is taken from the book "Gatsby" written by Ernest Vincent Wright in the late 1930's

The Amazing Psychic told her, "If I can write your exact weight on this piece of paper then you must give me 20 but if I cannot I will give you 20."
The lady looked around the room. There were no scales or anything else that could be used to find her weight. She agrees to the bet - certain that the Amazing Psychic could never guess her weight exactly.
In the end the lady had to pay the Amazing Psychic. 20. How did he win the bet?

c) What number can you subtract half from to obtain a result that is zero?

e) You have 10 bags of gold coins, 10 coins per bag, 10 grams per coin, but one bag of coins weigh only 9 grams per coin (because of low quality). How do you find out which bag contains low quality gold coins? You may use a scale only one time.

Three people check into a hotel. They pay $30 to the manager and go to their room. The manager suddenly remembers that the room rate is $25 and gives $5 to the bellboy to return to the people. On the way to the room the bellboy reasons that $5 would be difficult to share among three people so he pockets $2 and gives $1 to each person. Now each person paid $10 and got back $1. So they paid $9 each, totalling $27. The bellboy has $2, totalling $29. Where is the missing $1?
Two part question,

Suppose you're on a game show, and you're given the choice of three doors. Behind one door is a car, behind the others, goats. You pick a door, say number 1, and the host, who knows what's behind the doors, opens another door, say number 3, which has a goat. He says to you, "Do you want to pick door number 2?" Is it to your advantage to switch your choice of doors?
