Brain Games II - dare to enter ?

A man and a woman meet at a bar. After a long conversation they agree to have dinner the next day if the man remembers to call the woman to confirm the date. The next morning the man discovers that he can remember the digits in her number - 2, 3, 4, 5, 6, 7, and 8 - but he has completely forgotten their order.

If he decides to arrange the digits in random order and dial every combination, what are the chances that any given phone number will be hers ?
 
correct answer is 5040.
First number you have seven choices(7)
second number 6
third 5
fourth 4
fifth 3
sixth 2
seventh 1
7x6x5x4x3x2x1=5040

Darn it, I was making it way harder than it was. Shame on me! No wonder I dropped out from University.

you are human after all... i almost thought you were bionic..lol

i have loads of brain busters...


here's another one !



One grandfather, one grandmother, two fathers, two mothers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, one father-in law, and one daughter-in law attended a family reunion. If both halves of each relationship attended ( i.e., the father and the son ), how many people showed up ?
 
Ok I have a few simple trivia 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 2 years. Which room is safest for him?
 
2. A woman shoots her husband. Then she holds him under water for over 5 minutes. Finally, she hangs him. But 5 minutes later they both go out together and enjoy a wo nderful dinner together. How can this be?
 
3. Can you name three consecutive days without using the words Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday?
 
4. This is an unusual paragraph. I'm curious how quickly you can find out what is so unusual about it. It looks so plain you would think nothing was wrong with it. In fact, nothing is wrong with it! It is unusual though. Study it, and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out.
 
No. 4 took me the longest time (out of the 4) to work out...The others are probably not all that hard.....

So who is up for the challenge?
