The answer is the letter 'N'.

The riddle says 'take me out of a window and I leave a grieving wife'. Now if you think carefully and analyze some of the words in the sentence, you will find the answer to the whole riddle. In this case, the word is 'window' and if you remove the letter 'n' from the word, the word will become widow (I leave a grieving wife). Now the first sentence will make sense as if you read.

he second sentence says 'but stick me in a door, and I can save somebody's life'. Now in this sentence, the word 'door' is the one you need to analyze. If you add the letter 'N' in the word door, it becomes donor(I can save somebody's life). Did you answer this riddle correctly?

The correct answer is 1/2.

The chase that the first person in line takes your seat is equal to the chance that he takes his own seat. If he takes his own seat initially then you have a 100% chance of sitting in your seat, if he takes your seat you have a 0 percent chance. Now after the first person has picked a seat, the second person will enter the plan and, if the first person has sat in his seat, he will pick randomly, and again, the chance that he picks your seat is equal to the chance he picks someone your seat. The motion will continue until someone sits in the first persons seat, at this point the remaining people standing in line which each be able to sit in their own seats. Well how does that probability look in equation form? (2/100) * 50% + (98/100) * ( (2/98) * 50% + (96/98) * ( (2/96) * (50%) +... (2/2) * (50%) ) ) This expansion reduces to 1/2.
An easy way to see this is trying the problem with a 3 or 4 person scenario (pretend its a car). Both scenarios have probabilities of 1/2. Did you answer this riddle correctly?
