The Ticket Probability
My collection numbers 376 own cinema tickets. April 6th 1992 was the day when I stored the first, when I was 15 years old.

This collection is a unique fingerprint of my life in a specified period,
and we can’t preclude the chance that someone owns exactly the same collection.
I try to give an answer to this chance in the language of mathematics.
The probability can only be estimated since the number of cinemas and humanity had continually changed during this period.
