Our meeting tomorrow, Sunday, July 14, will be held at the Iowa City Public Library, Meeting Room B, from 2:00-4:00 p.m. 

Please bring a writing utensil and a notebook to the meeting. We will be playing Jeopardy! today.

Snacks will be provided. If you know anyone who is interested in coming, please bring them along!

The topic for this meeting will be Principle of Inclusion and Exclusion (PIE). Here’s a sneak peak of a problem: Six people of different heights are getting in line to buy donuts. Compute the number of ways they can arrange themselves in line such that no three consecutive people are in increasing order of height, from front to back.

In addition, the Counting, Part 2 handout is available in our archives. We’re sorry for the delay in publishing the solutions. They should be available early next week.

We’re looking forward to seeing everyone there!
