__________ 13. heads and a # < 5?
__________ 14. tails and a #2 or #3?
__________ 15. tails and 5th place?
__________ 16. tails and neither # 1 nor # 5?

the 18 bulls. A bull will not be ridden more than once.
__________ 17. What is the probability that the first rider will get
a black bull?
__________ 18. If the first rider gets a black bull, what is the
probability that the second rider will be assigned
a white bull?
__________ 19. What is the probability that the first and second
riders each get a white bull?
