I Stand Like A Sentry

I stand like a sentry
And am barred by the gentry,
The first month and its god oft slip
Between my hard, dun colored lip.

What am I?

Sentries are posted at borders, gates, or doors.
The gentry (in this case to referring to the general populace) bar their doors at night.
The first month is January, named after the Roman god Janus, the double-faced God of doorways, passages and thresholds.
You pass through the doorway (hence the slip), and dun is a brown color, referencing the color of wood, which most doors are made of. Though it’s not commonly referred to, the “lip of the door” is the part of the door that fits into the doorframe on the handle/knob side, particularly if the door is lipped or ridged in order to fit the door frame better.

Thanks to Helena for creating this and sending it in.

The Longest Double Letter Word

What is the longest unscientific English word that uses every letter in the word exactly twice? For example, noon has two Ns and two Os, but it’s not nearly long enough.

Happenchance. There are two Hs, two As, and so on for all the letters in the word. The longest scientific word with the same property is probably esophagographers.

Lending Money to Darlene

Franklin lent Darlene as much money as she already had, then she spent $10. The next day, Franklin lent her as much money as she now had and again, she spent $10. On the third day Franklin once again lent her as much money as she now had and she spent $10, leaving her broke. How much money did Darlene start with?

$8.75
You may have been tempted to guess $30 because $10 is spent three times, but that would mean she would have had $60 ($30 lent plus the $30 she already had), and $50 after spending $10. The rest of the numbers end up at higher than zero, so we know it has to be less than $30. Even starting at $10 leaves Darlene with $10 on the third day. Starting with $8.75 works out as follows.

Day 1: $8.75 (lent) + $8.75 (already had) – $10 (spent) = $7.50 (remaining)
Day 2: $7.50 + $7.50 – $10 = $5
Day 3: $5 + $5 – $10 = $0

Death By Marbles

You are a prisoner sentenced to death. The Emperor offers you a chance to live by playing a simple game. He gives you 50 black marbles, 50 white marbles and 2 empty bowls and instructs you to divide the 100 marbles into the two bowls. You can divide them however you want as long as all the marbles are in the bowls. You will be blindfolded and the bowls and marbles will be thoroughly mixed. You will then choose a single marble from one of the bowls. If the marble is white, you live. Black and you will be put to death.

How do you divide the marbles up so that you have the greatest probability of choosing a white marble?

Place one white marble in one bowl and place the rest of the marbles in the other bowl (49 whites, and 50 blacks).

This way you begin with a 50/50 chance of choosing the bowl with one white marble and living. Even if you choose the other bowl, you still have an almost 50% chance of picking one of the 49 white marbles. There are no guarantees in life, but this gives you the best change of surviving.
