The Day Of My Birthday
Hint:
December 31. Let's assume that December 31 is my correct birthday. Now let's also assume that I am 21 and that today is January 1st (the day after my birthday). That would mean that the day before yesterday (December 30) I would be 20. That fits the riddle so far, but here comes the tricky part!
Let's also say that the current year is 2013. So to clarify, today is January 1st 2013. Next year would be 2014, and the trick is that I will have two more birthdays by the end of 2014, one on December 31st 2013 (22 years old) and one on December 31st 2014 (23 years old).So in 2014, the year after 2013, I will actually turn 23! It's a tricky riddle. Best way to go about it is to use trial and error with all the answers and to also keep an open mind about what "next year" means. Did you answer this riddle correctly?
YES NO

The Same Birthday Riddle
How many people must be gathered together in a room, before you can be certain that there is a greater than 50/50 chance that at least two of them have the same birthday?
Hint:
Only twenty-three people need be in the room, a surprisingly small number. The probability that there will not be two matching birthdays is then, ignoring leap years, 365x364x363x...x343/365 over 23 which is approximately 0.493. this is less than half, and therefore the probability that a pair occurs is greater than 50-50. With as few as fourteen people in the room the chances are better than 50-50 that a pair will have birthdays on the same day or on consecutive days. Did you answer this riddle correctly?

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?

What Comes Immediately Before Today Riddle
If today is four days before the day immediately before two days after Wednesday, WHAT DAY comes immediately before the day that is two days after the day immediately after the day which comes two days before the day which comes three days after the day before yesterday?
Hint: Determine what "Today" is, then work backwards until you determine the day in question.
MONDAY. "Today" is Sunday. Now, starting at Sunday and working backwards (from "the day before yesterday"), we have the following: - 2 + 3 -2 + 1 + 2 - 1 ...So, we go from Sunday to Fri. to Mon. to Sat. to Sun. to Tues. to MONDAY. Did you answer this riddle correctly?
