Discrete Distributions Section 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. 18. Flip five unfair coins where, for each coin, P(H) = 0.35 and P(T) = 0.65. Let X be the total number heads. Find the variance for the distribution of X. A. 1.1375 В. 2.1375 С. 3.1375 D. 4.1375
