People are waiting in line to board a 100-seat airplane.
I am the first person in the line.
I get on the plane but suddenly can’t remember what my seat number is.
So I pick a seat at random.
After that, each person who gets on the plane sits in their assigned seat if it’s available, otherwise they will choose an open seat at random to sit in.
You are last in line.
What is the probability that you get to sit in your assigned seat?
3.
I live on the 10th floor of a building.
Every day I take the elevator to go down to the ground floor to go to work/shopping.
When I returns, I check whether the elevator is empty or not.
If the elevator is empty, I take the elevator to the 7th floor, & take the stairs to go to my apartment.
If there are other people in the elevator, I go to my floor directly.
Assuming I hate taking the stairs, how will you explain my actions?

A king has a cellar of 1000 bottles of delightful and extremely expensive wine.
A neighboring queen plots to kill the king.
She sends a servant to poison the wine.
Fortunately the king’s guards catch the servant after he has only poisoned one bottle.
Alas, the guards don’t know which bottle.
The poison is so strong that even if diluted infinite times it would still kill the king.
It will take 1 month for poison to show the effect.
King decides that he will get his 10 prisoners to sip the wine from all bottles.
He knows that he will be able to find the poisoned wine bottle.
He is sure that he will be drinking the rest 999 bottles of wine on his anniversary party.
His anniversary party is 5 weeks from today.
What is king's plan?
