STA198F: Probabilities Everywhere (Fall 2020, online synchronous)
This first-year-seminar course examines the meaning and mathematics of
probabilities, and how they arise in our everyday lives. Specific topics
may include: the nature of coincidences, the concept of luck, games
involving dice and cards, long run averages in casinos, margins of error
in polls, the interpretation of medical studies, crime statistics,
decision making, pseudorandomness, and Monte Carlo algorithms.
To succeed in this course, it is necessary to actively participate in
class discussions, and enthusiastically consider a variety of logical,
mathematical, and societal issues from a variety of perspectives.

Be sure to obtain this textbook (either hardcopy or electronic)

Here is some information about using Zoom in this class:
- The Zoom link will be emailed to all enrolled students before
the first class. That same link will work for all the classes
(and also for any office hours, etc).
Please save and bookmark it. However, please do not post it
publicly, to avoid zoom-bombers.
(If you have not received the Zoom link by now, then please email the
instructor to receive it.)
- You should connect on Zoom before the class start time of 3:10,
hopefully between 3:00 and 3:05.
- Please connect from a quiet room, where you can be alone
without any distractions.
- If possible, use a laptop or desktop computer, not an iPad
or cell phone -- and the actual Zoom app, not the web browser version --
for best Zoom funcationality and viewing.
- Please leave your computer's camera on,
so we can all see each other.
- Optionally, you may wish to mute your microphone when you are
not speaking, to prevent any background noises from disturbing the class.
- If necessary, use "Rename" on Zoom to have it
display your usual first and last name (but not your student number).
- You should pay close attention during class,
and refrain from sending or reading any private messages, emails,
Facebook posts, etc.
- If possible, try to print out the day's handout(s)
and your homework answers in advance, so you do not
have to switch between computer windows during class.
- For most of the class we will all be together in the same Zoom main
room. But sometimes we will switch to small-group work, where you will be
given a group assignment, and then moved into separate Zoom breakout rooms
with about 3-4 students in each.
- During whole-class discussions, I will select Zoom's "Gallery View",
to see the entire class at once. You can select either Gallery View or
Speaker View, whichever you prefer. But in the small-group breakout rooms,
you should select Gallery View to see all the other people in your group.
I created a general STA198 Discussion Page on the course's
where students can post comments and questions about the course.
Feel free to post course-related messages there any time you want to.
I may or may not read your posts myself, but other students can answer
them whenever they wish.
(I also tried creating a
piazza discussion page,
though I'm not sure we need it. If you want to use it, but
have trouble connecting, then let me know.)
You may also wish to form a study group or join a drop-in

- Classes will involve both student cooperative work in small groups (in
Zoom breakout rooms), and whole-class discussion sessions.
- Students are expected to punctually attend class each week, to
enthusiastically participate in discussions and activities during class

It is crucial to have

to show interest and enthusiasm in class activities,
and to speak up often
and listen carefully to others
during whole-class discussions.
- Weekly homework will often involve reading from the textbook
or other source, and answering various questions about what you have read.
