People
are waiting in line to board a 100-seat airplane. Ashish is the first person in
the line. He gets on the plane but suddenly can't remember what his seat number
is, so he picks 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.
The flight is full and you are last in line. What is the
probability that you get to sit in your assigned seat?
HINT:
Consider these two questions
What happens if somebody sits in your seat?
What happens if somebody sits in Ashish's assigned seat?
