**Welcome to Math
205: Probability!**

**Current Announcements:**

If you’re
interested in helping build the world-record setting, largest-ever Sierpinski triangle made out of K’NEX pieces, then this
event is for you. The organizer, Bryn Mawr math professor Victor Donnay,
is looking for people to help run the event.
If you’re interested, you can either contact him directly, or let me
know, and I will put you in touch.

We will
use *Mathematica* in class on Wednesday, April 24. Please bring your laptop!

If you
didn’t get your full 10 points of extra credit last week, here is one more
opportunity: What can you do with a math
major after you graduate? Here
are the details about the **math major alumnae panel** happening tomorrow
(Tuesday, April 23, 7pm, Park 338). If
you sign up for pizza, there will be some for you. Even if you have the maximum extra credit
already, you should still consider attending the event. You can learn how former Bryn Mawr math majors found their current employment, what they
wish they had done as undergraduates to prepare, whether or not their firms
offer summer internships, and so on.

I had
originally planned to due presentations during the last week of class, but now
I will let you schedule yours for any time during the last week of class or
during the final exam period. Do,
however, still be prepared to hand in part 2 of your portfolio on or before the
last day of the semester. Here
is the checklist.

We will have a quiz on chapter 8 on Wednesday,
April 24.

Here are the blank versions of the quizzes: 4, 5.1,
5.2,
6,
and 7.

**Current Assignments:**

*Due
Wednesday, April 24:*

Reading
Guide for Sections 9.2 and 9.3

Invent
two probability problems. Provide the
scenario, details, questions, and answers for each one. The problems should be realistic, and
represent a nontrivial application of one or more concepts we have learned this
semester. Creative and interesting real-life problems will be considered for
use in class, and will be worth 5 points (each) of extra credit that counts
towards writing problems. Here
are some examples.

*Due
Monday, April 29:*

Section
9.1 Exercises: 1, 5, 7, 10*

Please
write up exercises marked with an asterisk (*) in LaTeX,
and keep hand them in separated from the rest of the assignment.
