Brad Pitt & Angelina Jolie decided to marry in INDIA. So they booked two tickets in a flight.
Angelina Jolie was the first to board to flight to Delhi.
She forgot her seat number and picked a random seat for herself.
After this, every single person who get to the flight sit on his seat if it's available, else chose any available seat at random.
Brad Pitt was the last to enter the flight and at that moment 99 out 100 seats were occupied.
So, Whats the probability of Brad to sit in his own seat ?
Difficulty Level - 3/5
