Hint:
Shortcut Through The Woods
4 friends were walking home when they decided to take a shortcut through the woods. It begins to rain and they cannot find their way out of the woods since it becomes dark out. So they find a cabin and decide to stay in it till Morning. The cabin has no lights and no windows so it is pitch black. Scared, the 4 friends huddle together in the middle and decide to do the whole: 1 person stays awake to keep watch while everyone sleeps and they'd switch off every hour. But this plan didn't work as everyone was too scared to sleep. So they decided to play a game until sunrise. Each of the friends went into one of the four corners of cabin and played a game. one person would run out of their corner along the side of the cabin and tag the next person on their back and take their place. That person would then do the same as the last person and they would keep going at this till morning. They kept playing the game over and over till one of the friends realized something wrong and screamed. What did that person realize?
Hint:
As soon as the 3rd person was tagged they'd run to a corner where no one is standing since person 1 is at corner 2, person 2 is corner 3 person 3 is corner 4.

Hint:
Born In Mourning
I have a name, but it isn't my name. My face shows signs of age. I always mean the same thing, no matter what I say. I'm born in mourning, and I last 'til the end of days. Men plant me, but I never grow. They run from me, but I never move. They look at me and see their future, rotting in the fields where I bloom. What am I?
Hint:
The Secret Santa Exchange
A group of ten friends decide to exchange gifts as secret Santas. Each person writes his or her name on a piece of paper and puts it in a hat. Then each person randomly draws a name from the hat to determine who has him as his or her secret Santa. The secret Santa then makes a gift for the person whose name he drew.
When it's time to exchange presents, each person walks over to the person he made the gift for and holds his or her left hand in his right hand.
What is the probability that the 10 friends holding hands form a single continuous circle?
When it's time to exchange presents, each person walks over to the person he made the gift for and holds his or her left hand in his right hand.
What is the probability that the 10 friends holding hands form a single continuous circle?
Hint: It's not as difficult as it seems.
It's the number of ways the friends can form a circle divided by the number of ways the names can be drawn out of the hat.
1/10
For a group of n friends, there are n! (n factorial) ways to draw the names out of the hat. Since a circle does not have a beginning and end, choose one person as the beginning and end of the circle. There are now (n-1)! ways to distribute the remaining people around the circle. Thus the probability of forming a single circle is
(n-1)! / n!
Since n! = (n-1)! * n (for n > 1), this can be rewritten as
(n-1)! / (n*(n-1)!)
Factoring out the (n-1)! from the numerator and denominator leaves
1/n
as the probability. Did you answer this riddle correctly?
