Read 4.5-4.7, 4.10
Section Number Points Comments
4.3 35(b),(d) 4 DAM2: 4.8, 3(b),(d)
36 DAM2: 4.8, 6
4.5 2 2 DAM2: same problem - Do this and all the other
two problems in this section both algebraically
and combinatorially
4 6 DAM2: same problem
6 6 DAM2: same problem
4.6 2(a) 3 DAM2: same problem; use the binomial theorem (don't just use a calculator!)
6 4 DAM2: same problem; don't forget to say how it's relevant to the previous problem
8 3 DAM2: same problem
4.7 4 3 DAM2: same problem
8 3 DAM2: same problem; assume u >= b. Hint: there's an easy answer.
9 3 DAM2: same problem
15(b) 3 DAM2: same problem; you must model this as a balls and urns problem
4.10 2 3 DAM2: same problem
8 3 DAM2: same problem. Warning: this problem is hard (although it has a short proof)
