Monday:
 Study: 2.1, 2.2, 1.4 (for explanation of notation)
 Do: 1.(The Priciple of Inclusion and Exclusion) Suppose in some set, a elements have
property A and b elements have property B, anb elements have both properties. How many
elements are there that have at least one of the two properties?
 2. (The Rule of Sum) Suppose in some set of aUb elements, anb elements have both property A
and property B, and b elements have property B. How many elements have only property a?
 3. (The Product Principle) Suppose you have a possibilities for the first item on a list and b
possibilities for the second, and your choice for the first thing on the list doesnt affect
your second. How many different lists can you make? Suppose you have a possibilities for the
first item, b for the second, c for the third, and so on, and no choice affects any other. How
many different lists of length 10 can you make?
 4. (Extension of the Product Principle) Suppose you have a set of size n. How many lists of length
k can you make without any item repeating? Of length n?
 5. Label each part of the first 16 problems (of the handout) with which principle or rule should
be used in solving it.
 6. What is one "big idea" from today's lesson? How will you remember this? (Hint: Studies show that
one of the easiest ways to remember something is to connect it to personal experience, either directly or
by analogy.) 7. What is a test question you think you might be asked about an important concept from today's lesson?
