# Homework Assignment #3

#### Posted Thursday 29 March 2007

#### Due on paper in (discussion) class, Wednesday 18 April 2007

There are thirteen questions for 100
total points. All are from
the textbook, *A Mathematical Foundation for Computer Science*,
by Barrington. (These problems are from Chapter I, which was distributed in
lecture on Monday 26 March.)
The text has both Exercises (with solutions in the back)
and Problems (without solutions) -- these assignments are Problems so make
sure you don't do an Exercise by mistake.

The number after each problem is its individual point value.

Students are responsible for understanding and following
