Note: The answer for 6.1, 11a in the back of the book is incorrect, but the work there should provide a hint. Also, show your work completely for 11b, copying the book is not enough.
Assignment #12--Due Friday, April 23

Notes: For 6.2 #16, the order in which
cards are dealt matters, e.g. dealing 9h,9d,9s,9c differs from dealing
9d,9h,9s,9c. Similarly for 6.2 #19, it may be helpful to consider the dice as
being colored, so that rolling a 2 on a red die and a 3 on a blue die differs
from rolling a 3 on a red die and a 2 on a blue die.
