# Probability of $$Tickets$$

Suppose i am in a big hall , there i gave 5 tickets (each carrying distinct specific codes) to each of the 50 persons. now I ask all of them to exchange their all 3 tickets

now the question is what is the probability that a person gets at least 1 original ticket i.e. ticket he was given initially

please generalize it also
