Seating |
A theatre has 137 seats and every ticket is sold for this evening’s performance.
The theatre goers arrive in random order. Unfortunately the 17th theatre goer
is drunk and goes to a random seat, instead of his assigned seat. He sits down
and immediately falls asleep. Subsequently, when a patron arrives and finds
their seat already taken, they take a random seat. What is the probability that
the last patron finds their assigned seat empty?
