Ticket Machine Setup Suppose you have a machine that randomly prints out tickets with numbers on them. 17% of the time the ticket has number 3. 24% of the time the ticket has number 8. 37% of the time the ticket has number 15. 22% of the time the ticket has number 22. There are no other ticket numbers. Let the random variable X be the number on the ticket.
