Note most quizzes will be 5 minutes in length and are meant to cover basic material. Thus if you are not averaging an A on quizzes, you are probably failing this class. This is really true. Past classes bear strong witness to this fact.
Thus for each quiz, make sure you study the basics as outlined in each quiz study guide (click on SG for the appropriate quiz for the Study guide.
You will have more time on exams, so exam questions can be more challenging (so practice more than just the basics).

Define: P(n, r), C(n, r) both mathematically and in words:
Mathematically: P(n, r) = n!/(n-r)!, C(n, r) = n!/[r!(n-r)!]
P(n, r) = the number of r-permutations of a set S where |S| = n
C(n, r) = the number of subsets with r elements from set set with n elements.
Define: r-permutation, r-subset, multiset.
Calculate simple problems such as number of subsets, P(n,r), C(n, r), permutations of multisets including unlimited repeats, limited repeats, and determining number of non-negative integral solutions to x1 + x2 + ... + xk = r.
