You enter a stadium with 1000 seats. you are told that under one of the
chairs is a prize. You choose a seat randomly.
q1, what's the probability your seat has a prize
q2, now 990 seats are removed, not including your seat or the one with the
prize under it. There are 10 seats left. What's the probability that your
seat contains the prize now?
Who knows how to solve this problem?
Thanks a lot!
