5/10: Group A: Geometric Probability and Expected Value
Group B: Finite fields and their applications in combinatorics and cryptology (Prof. Kirby Baker)

Group A: Here are some HW problems: 10.2.2, 10.2.3 10.3.2, 10.3.4 11.2.1, 11.2.2 Challenge: 10.17, 10.21 Group B: What are finite fields? We'll answer this question and you'll see that you are already familiar with many of them, in a different guise. There are some nice applications that are easy to understand; we'll look at a few.
